Gadgets are just that, gadgets. The main things that I use are a self healing mat, a rotary cutter, and a 6 x 12 ruler. Anything past that is a gadget that I like but do not NEED. I would have him get fabric. As much as he can. Every time I see the prices that you are forced to pay I cringe. I often wonder how you can afford to quilt. Get a catalog and pick the fabrics that you like, and then he can get similar. Can you bring back color catchers? That might be something to have him get.
