I think you are a rare bird. (No offense intended!!) Most of us seem to have so many ideas crammed into our brains it is hard not to have two or three or (pick a number) of projects started, and about a hundred more on our to do list.
you must have a nice organized brain - unlike mine, which is always swimming with ideas and plans. It gets muddy in there sometimes...
Look through patterns, magazines, pictures on this site, your fabric - and I bet something will click!
Let us know what you start.
