As for me, I find it perfectly natural to have more than 10 projects going at the same time. I do a little cutting here, then some sewing, then some squaring up, then some more sewing, then a pack up a tote with things to work to undo or cut, along with a few magazines/books to review, at home once again to do some pinning of finished tops, more sewing, makes plans to go shopping with quilt buddies for more stash, on occasion sew scraps together to make odd blocks for miscellaneous projects, more serious sewing, clean my machine when the lint bunnies start appearing and the list goes on. It may sound hopeless but I actually have 3 large see-thru rubbermaid tubs filled with over 50 unfinished projects and this is normal for me but I actually work well in this kind of environment. I work on quilts, clothing, handsewn stuffed animals, sewn household items and the list goes on because along with my regular job, my hubby and I do craft shows. My #1 goal is to always work on clearing one of them out with a finished projects before starting new projects. I have to admit it's soooooo tempting when I'm at fabric stores and I see all the new lines of colors/values and new project/pattern ideas but it's how I keep myself under control. Now some of you may be laughing at this or think I'm just crazy but it works for me and I never get bored of anything I'm working on.
Sewing was my salvation when I quit smoking over 20 years ago - it's just as addictive, but so much more fulfilling, so much fun. And just so you know that as a new quilter you too will find what works best for you with time. Right now make yourself a goal and stick to it. That way no one can say she was inudated and you won't get burned out either with too much to get done or no time to do it all.
