OK, here I am and I'll try to make a little tutorial to show you how I asseble my finished blocks with the QAYG method.
Take two blocks. Be sure they are 5".
Cut two sashing strips, one 1" and one 1 1/4".
Add the 1 1/4" sashing to the back of your block pinning in place, then add the 1" sashing to the front of your block and pin in place.
Sew all this sandwich together using a 1/4" seam allowance.
Flip the front sashing and press, put the second block right sight on top of the sashing, lining up the raw edges. Pin in place and stitch again using 1/4" seam allowance.
Press your sashing. Now your blocks are toghter on the front.
Flip over your blocks to the back, turn under your sashing and make sure it is 1/2" wide. Slip stitch the sashing into position.
DONE!! Now join all your blocks together like this and join the rows with a long sashing that measures the complete lengh of you row.
