I just got this from Thimbleberries

I just got this in my email, from my Thimbleberries Newsletter, and I wanted it to be available when I wanted it and not have to memorize it. If you can use it too that will be great. I do lots of designing myself so it is good to have this information.

Half-sizing squares
Example One:
• If your cut size is 4-1/2", subtract the (2) seam allowances (1/4" each side)
4-1/2" minus 1/2" equals 4"... divide that in half which equals 2",
then add the (2) seam allowances back on...2" plus 1/2" equals 2-1/2" which is your new cut size

Example Two:
• If your cut size is 1-1/2", subtract the (2) seam allowances (1/4" each side)
1-1/2" minus 1/2" equals 1"... divide that in half which equals 1/2",
then add the (2) seam allowances back on...1/2" plus 1/2" equals 1" which is your new cut size

Half-sizing triangle-pieced squares
Example One:
• If your cut size is 6-7/8", subtract 7/8".
6-7/8" minus 7/8" equals 6"... divide that in half which equals 3",
then add the 7/8" back on... 3" plus 7/8" equals 3-7/8" which is your new cut size

Example Two:
• If your cut size is 7-7/8", subtract 7/8".
7-7/8" minus 7/8" equals 7"... divide that in half which equals 3-1/2",
then add the 7/8" back on... 3-1/2" plus 7/8" equals 4-3/8" which is your new cut size

Have more quilts in your life.
