Mkotch - it's a good plan to make a change if it's no longer being fun for you. There are no awards to earn by sticking with something exactly like the pattern. I think that is one reason I prefer not to work off patterns, then I don't have any qualms about going my own direction.
I got sick of everything I was working on, and pushed it all aside and started making blocks for the BOHO Heart. I've got all the 10" and almost all of the 8" done. I'm really looking forward to making the smaller blocks, but am thinking of doing more variety and no applique.
