Oh, boy. I can never answer that question when people ask me how long it takes me to make one of my quilts. I have no clue. I can tell you, though, when I make something "artsy" it takes me a long time. My creative process is slow and I agonize over every decision ... even on this one when I basically copied a picture in Ricky's book!!!! One problem I encountered was that I only had fat quarters of this hand-dyed fabric and I was running out of big pieces towards the end and couldn't decide how to do the border. So I put it on my design wall and looked at it for a couple weeks!!
Well, I know I didn't answer your question at all. If you have a firm idea in your mind of what you want to do, it wouldn't take long at all.
