I started a small quilt group at my church to show a few ladies how to quilt. Well, one lady wanted to make a shaggy denim quilt from her hubby's jeans. So, we make rag quilts. My mind then begins to think I could make a denim quilt for my 3 children and spouses. Now that's one for my bed and 6 for kids and company.
I say all this to explain, you are not alone. We all have many quilts bouncing in our brains while we are currently working on something else. That is how we get WIP's (work in progress) and UFO's (unfinished objects) in our collections.
Don't be tough on your self. Start with something small and simple and work at your own progress. Good Luck.
