This part took perhaps more time than I expected, but was a really interesting experience.
I walked down aisle at the fabric store, closing my eyes sometimes, just looking away others, and just tried to feel the fabrics. I was immediately drawn to the soft fleeces, and the luxurious velvet (bought a really small piece of that). But the quilt couldn't feel all the same, so I also found some suede, and synthetics, and at home I added denim, and burlap from a rice bag for a rough texture.
Not only did I want the feels to be different, but I wanted the colors to be contrasty enough when placed next to each other, so that the Grandpa could still use the little bit of eyesight he has.
So in total I have 9 different feeling fabrics. And a larger piece of fabric to use for the back and border.
Also needed for the sewing portion:
Velcro (less than an inch)
sewing machine (although it would be beautiful by hand)
