I'm planning 49 blocks for the Grandmother's Choice sampler.
If you are thinking about yardage for sashing and borders how about this sampler set for 49 blocks.
2" Finished sashing strips and corner stones
6" Finished mitered borders
84" x 84"
I drew this up in Electric Quilt and then I used the yardage calculator to figure out the yardage for the sashing and border.
Here's what it says---and I added my own words too above.
A 7 x 7 layout of 49 blocks finishing to 8"
You need 64 cornerstones cut 2-1/2" square = 3/8 yard
112 sashing strips cut 2-1/2" x 8" = 2 yards (THAT'S 8-1/2"---THANK YOU MARCI!)
1-3/4 yards (if they are pieced selvage to selvage) for the border.
If you use long strips parallel to the selvage: 2-1/2 yards. Cut 4 strips 6-1/2" x 84-1/2" and miter them.
For 49 different 8" blocks 5 yards in all should be enough.
1 yard each of the following 5 values:
- Really dark
- Medium dark
- Medium light
- Really light.
If you were going to do a 2-color quilt, say red and white:
3 yards of each of the two colors should be plenty for the blocks.
Buy a yard and precut what you need. Use the rest for one of your block fabrics.
Buy 6 yards of backing fabric and piece it. You can also use extra wide backing fabric. My Moda collection Metropolitan Fair has a backing fabric that is 108" wide. The Oyster Shell Gray might be good. Look for it in October. (#11076-18)
