You say you are saving it for a quilt for yourself- well find a pattern that you love and make yourself a quilt. Maybe start with a throw size - it sounds like you are nervous about the whole process ( even if you don't mention it ) from the cutting , picking the colors, to the sewing/matching seams . You have to allow yourself to make mistakes - become friends with (Jack) the ripper. And if it doesn't come out perfect that is fine also
I make my quilts to be loved - not show stoppers.
Are you thinking you talents won't match what the others in your group can do ? We all start as beginners and take baby steps - practice -practice-practice. And making charity quilts is a wonderful way to practice
Take a couple deep breaths and enjoy - and remember these wise words I have heard here MANY times - what does it look like when you are on a galloping horse going fast- can you see the "mistakes" ?
