A dear elderly lady used to make quilts for all the "kids" who graduated from high school and attended our church. My two kids were the grateful recepients of these quilts. For some reason my daughter's was made of satin. These are slightly larger than a lap quilt - almost twin sized. Well, her quilt was so "her" - all girly and stuff - she loved it, but ... couldn't keep it on. Taking a nap on the couch? Quilt would slide to the floor. Laying down for just a minute and pull that quilt up over you? Not for long! Slip slide away!
That dear lady is now nearly 100 years old and lives in a care center. I told her just the other day that I was taking over the Senior Quilt gift project. She was delighted. But ... I won't be making any from satin!
There aren't memory quilts - just plain old simple things - but the kids used to have such fun wondering what theirs would be like and taking them off to college with them.
For sashing I can imagine it would be lovely! Good luck!
