New to Quilting?

If you are brand new to quilting and don't know where to begin, start with the posts in September 2011 (look in the blog archive). The first four posts cover basics such as choosing equipment, choosing colors, how to sew 1/4" seams, how to use a rotary cutter, and how to press (not iron) your block during construction.

Drawing Diagonal Lines on Fabric

Sometimes I have a hard time drawing the diagonal line on squares. The line doesn't end up straight because the fabric shifts under the ruler as a use the pencil to draw the line.

Here's what I came up with:

I use a sheet of 220 grit Wet or Dry sandpaper.

The grit is very fine and holds the fabric so that it doesn't shift.
I use a ruler and a mechanical pencil. The mechanical pencil makes a very fine line and it is easy to get the line right on the edge of the ruler.

The lines are all straight, the fabric hasn't shifted and it hasn't stretched along the bias.
It works for me. If you have another way of drawing the diagonal line on your squares please leave a comment and let me know!

Double Quartet (aka Turned Around) — Quilt Block Tutorial

Double Quartet (aka Turned Around)
8" finished quilt block
This is an easy block! I love the way it looks.

Step 1: Cutting the Fabric

Fabric A: background fabric
  • A1 - cut four 3" squares
  • A2 - cut four 2 1/2" squares
Fabric B: grey (medium color)
  • B - cut four 2 1/2" squares
Fabric C: blue (dark color)
  • C - cut four 3" squares



Step 2: Half-square Triangle Units
Hopefully half-square triangle units are getting easier to sew!

Draw a diagonal line on the back of each A1 (3" square background fabric) from one corner to another.
 Place each A1 (background fabric) right sides together with a C (blue or dark fabric).
Pin the pieces together so they don't shift while sewing.

Sew a scant 1/4" seam on either side of the drawn diagonal line. I used black so you could see the stitching line easily.

Cut along the drawn line to make eight half-square triangle units.

I pressed my seams open. This time I put the half-square triangle unit on top of a sleeve form and ironed it. It was much easier and faster to press it open.

All eight half-square triangle units pressed open.
Not shown: trim each unit to 2 1/2" using whatever ruler you prefer. 
I like using both Marsha McCloskey's 6" Precession Trimmer and Quilt in a Day 6 1/2" Square Up Ruler. I grab whichever one is on the top of my stack of rulers.

Step 3: Sewing the Block Together
Lay out the half-square triangle units, the A2 (2 1/2" background squares),  and the B (grey or medium 2 1/2" squares).
See how fast this block is? 
 
Press the seams open.
There is no way to nest the seams if they are pressed open so make sure you pin the rows together before you sew them! If you click on the photo below you will see that even with pinning, sewing with pressed open seams takes practice. My corners don't match up exactly.
I don't worry too much unless the seams are off a lot. By 'a lot' I mean that I could see the problem from 9 feet away! Sometimes I rip a seam out and sew it again to improve the block, but sometimes it's good enough because no one will notice the mistake.
If your cutting and sewing is accurate you shouldn't have to trim much more than loose threads when you are done sewing the rows together.

Chisholm Trail – Quilt Block Tutorial

Chisholm Trail
8" finished
8 1/2" unfinished
I'll be sewing the rest of the blocks in this quilt with the seams open. It's an experiment to see if it really is easier to quilt after the top is put together. It takes more time to sew the block when the seams are pressed open. The two reasons for that are it takes a bit longer to press the seams open than it does to press them to one side, and it takes a bit longer to match the seams since there is no way to nest the seams.

Step 1: Cutting the fabric

Fabric A: background fabric
  • A1 - cut one 5 1/2" square (for the flying geese units using Quilt in a Day
  • A2 - cut three 3" squares (for half-square triangles)

Fabric B: red (main color)

  • B1 - cut one 3" square (for half-square triangles)
  • B2 - cut one 7" square

Fabric: grey polka dots (neutral or medium color)
  • C1 - cut two 3" squares (for half-square triangles)
  • C2 - cut two 2 1/2" squares

Someone told my daughter that if you have to trim your block units (half-square triangles, flying geese, etc) then you aren't a 'true quilter.' My thought is that each quilter should use whatever method helps them to achieve the results that they want.

When sewing half-square triangle units I always teach new quilters to cut the squares a little bit larger and trim the unit to the right size. The amount of fabric that is thrown away is negligible, and the blocks are so much easier to piece when the smaller units are the exact size needed!

Step 2: Drawing Diagonals and Sewing Half-square Triangle units, starting the Flying Geese units.

I'm using the Large Flying Geese Ruler by Quilt in a Day to make my Flying Geese units. If you have a different method you like, you'll have to adjust the cutting directions in Step 1.

I sew all my seams a scant 1/4". You should do a few samples to make sure that however you are sewing your seam will give you a 1/4" seam. If you need a refresher or reminder on how to check your seams, visit this post.
 
Draw diagonal lines from corner to corner on all the A pieces.
Place one A2 and the B1 piece right sides together and pin.
Place an A2 and both C1 pieces right sides together and pin.
Carefully center the A1 square right sides together with the B2 square and pin in four places.

Sew a scant 1/4" seam on both sides of each diagonal line.

Cut along the diagonal lines.

Press all seams open. Trim the half-square triangle units to 2 1/2". They are done.
I like to start laying out my block as soon as some of the pieces are done. It helps keep me organized and know what step I'm on.

 Step 3: Finishing the Flying Geese Units


Do not match the center seams of the A1-B2 pieces! Match the four corners! Place a white triangle right sides together on the red triangles, as in the photo.

Draw a diagonal line that goes from the corner of A1 through to the opposite corner of B2.
Notice that all four corners of the A1-B2 pieces match.
Sew a scant 1/4" seam on both sides of the drawn diagonal line.

Cut along the drawn diagonal line. Press seams open.
Your pieces should look like the ones in the photo.

Use your Flying Geese ruler. Line up the red triangle of the ruler with the seams on A1.
Make sure the point of the ruler is over the sewn point on the block.
If you click on the picture it will enlarge and you can see it better.
Trim all three sides.
Flip the piece and center the ruler matching the seams. Trim the last part of the Flying Geese unit.
 The directions that come with the ruler are excellent. If you have the ruler, use the directions, too! You can also click on this link for a more detailed tutorial on using the ruler.

Step 4: Sewing the Block Together
 
Finish laying your block out on a portable surface. I use my design and pressing board.

Sew the center square first. It's wrong side up in the photo above.

It's worth the extra effort to spend the time to match your points. They won't always be perfect, but the more you practice getting them to match, the better and faster you will be at getting good corners.
The center should measure 4 1/2" square.

Lay all the block units out. I prefer to sew in columns, but some people like to sew the rows first and the columns next.

Make sure you pin the columns together where the seams match. When the seams are pressed open there is no way to 'nest' them. I used pins every place the seams needed to match.

Road to Oklahoma – Quilt Block Tutorial

Road to Oklahoma
8" finished
Step 1: Cutting the fabric

Fabric A: background fabric
  • A1 - cut six 2 1/2" squares
  • A2 - cut two 3" squares
Fabric B: grey (medium color)
  • B1 - cut two 2 1/2" squares
  • B2 - cut two 3" squares
Fabric C: blue (dark) 
  • C - cut four 2 1/2" squares

Step 2: Half-square Triangle Units
I'm trying something new for the rest of the blocks in this quilt. I'm going to press the seams open. Quilters like Leah Day press all their seams open because it makes it easier to machine quilt, especially on a home machine. Here's a link to an article by Candace Eisner Strick about how to press seams. She says it depends on the seam bulk in the block. If there is going to be quite a bit of bulk then she presses her seams open.

Pressing seams open does take longer than pressing to the side. I'm also tempted to invest in The Strip Stick to help with pressing seams open.

Draw a diagonal line on both A2 squares.

Remember to pin the pieces together so they don't shift while you are sewing.
Sew a scant 1/4" seam down both sides of the drawn diagonal line.
Cut along the drawn diagonal line.

Press seams open.

Trim blocks to 2 1/2" square.

Step 3: Sewing the Block Together
Place your blocks on your Design and Pressing board, cutting mat, or whatever you use to bring your block to your sewing machine.

Sew each column of blocks together.
Sew the rows together matching the seams.
I used a pin to match my seams up.


Press from the right side and trim to 8 1/2" square.
Hopefully your cutting and sewing are so accurate you won't have to trim more than a few stray threads.
You can see in the photo above that I'm not a perfect quilter. There is one place where the point doesn't match up very well. Part of that is getting used to seams being pressed open instead of nesting them together.

I think I've fallen in love with the grey polka dots! I may use that fabric in every block from now on. 

I've included a great video called Seams Common Sense with Jennie Rayment and Valerie Nesbitt. The two have a great discussion on the pros and cons of pressing seams open.
