Thinking out loud: starting a hobby group that'll knit, crochet and/or sew acrylic squares to be assembled as blankets/mats for donation during times like these. We stockpile during sunny days and distribute when needed. Something to manifest soon...

 A square should be 5x5 inches or 10x10 inches made of high bulk/worsted weight acrylic.
I chose this size since one 15-gram acrylic ball, Red Heart, yields a five-inch square with extra yarn for joining together. Let's avoid white and pale colors but variegated ones with some white/pale colors are OK.

 We'll also eventually need volunteers who can sew/crochet these squares , after we collect enough squares.
