Even though I like some of the books for precuts, other than an occasional charm pack, I usually cut my own. I did buy a Turnover pk. on sale recently & am playing with it now, cutting each triangle in half, by the way. Doing some star blocks, with all triangles, adding some tone on tone cream for background, & they are turning out pretty!... Not worth, in my mind, or pocketbook, to pay full price for most of these precut packs though!...
