Make em all, Janet! Like Rhonda said, give a project 15 minutes, then you can set it aside -- and start another if you want! It's your hobby and there's no one right way to do it.
When indecision grips me, I look for baby steps. I have 14 quilts in progress and none are inspiring me right now. I really want a new one but am trying to whittle down the pile before I start more.
So last night I marked a medallion for ruler work (baby step), sewed up scraps for the Irish Chain because they were left out and in my way (baby step). And then ripped apart several project bins when I realized these were quilts in the fabric pull stage that I was no longer interested in. That last bit felt so good.
I might just do fabric pulls for quilts I'm dreaming about to take the edge off my desire to start new quilts. Or break my vow and just make a new top because there are no rules!
