You can scan in your fabric or blocks and something I found that I totally love is to be able to take any picture, import it, and then trace a transparency of it using the drawing tools and snap-to grid measurements. That's how I got the teddy bear block into EQ6, a 24" block from Quilter's Cache.
I've often seen pictures and thought if I could do that picture with fabric...
I have an older Stash CD and don't they come out with one every season with all the designer fabric collections?
