WOW! this is sooo pretty, and yes, the quilting was the icing on the cake. I have no idea about a pattern at this moment, but I did a little research on alzheimers. I have 2 very dear friends going thru that now. Experts! advise giving different things to Alzheimer patients to 'help'..like balls, a quilt od circles(love them myself!), nature calms alzheimers patients, so any animal quilt would be good. Also they recommend giving blocks, dominoes, & crayons,paints to help. So I was thinking any of these would help represent alzheimers. I am sue we could find lots of quilt patterns to represent these items also. Actually your quilt reminds me of playing blocks! or the game tangle, which is advised to give to patients.It is so great what you're doing, I wish you the best.
