Dear Melissa, so many ideas !! I like your idea of a sampler, especially if Grandma appreciates quilts. Also it will be a good learning experience for you. I'm the same as you when it comes to buying enough fabrics to use in each of the blocks. No one has ever really given me an answer, so I just but a lot. :lol: It can always be used on something else later.
Have fun making this for Grandma and God Bless You, Grandma, and her caregivers.
