Hello - I mailed out over 100 letters with the center white piece with directions. Some people use the pens, some embroidered, some used stamps. The grandchildren had their own 6 inch square piece to draw a picture on. How cute was a stick picture of Matthew and his Grandma playing Go Fish... I presented my mother with the quilt pieced, layered and a few quilting stiches in place. The next summer I had finished the hand quilting and presented it to her at her family reunion. You will love going to the mail box to see what arrives. My mother wondered why there were so many birthday cards that year on her dining room table !! Have fun with the experience. Do give people a date for them to have it back to you or they will procrastinate.. Put freezer paper on all of them or bring along lots of extra fabric. Thank you for allowing me to think about good memories...
