Great advice & some frugal tips from everyone so far.
*I agree with cjomomma- there are easier ways to make HSTs without a triangle template, but a must is assorted size rulers & square templates.
*I think 2 sizes of rotary cutters would be good.
*Oooh, one of every size Ginghers that Deedles listed (wouldn't that be heaven?)
*A design wall (a vanishing design wall would be really cool!) In following raptureready's cheap alternative lead, I use a big flannel backed tablecloth.
May all your Christmas wishes come true!
