Ok, BellaBoo, now you have to let us know what you think of it. I, too, have The Block Tool, but it is very limited. It shows only blocks with set colorations. YOu can't change or upload your own colors or fabrics.
Yes, I could do it in EQ, but if I visualize using it at the store to play around with fabrics before I buy them. Maybe I can rationalize it by saying I won't be buying fabric that doesn't fit my stash. Of course, it would take quite a while to enter all the fabric I have. I don't know if I'll buy it, but it's something to think about. Please let me know if you really like it.
