I was given 12 of these hand quilted and embroidery blocks to finish up and do with as I wish.I cut 1 inch sashing strips (1 1/8 is just a tad bit better to work with) and started by sewing a strip to the back side of the block a little less than 1/4 inch in. You can use a basting stitch if you prefer. The goal at this point is to tack the back in place.
Open up your blocks, wrong side facing up.
Apply glue or Steam a Seam inside the seam allowance on the block without the sashing strip.
Fold 1/4 inch on your sashing strip and press.
