I have a very small sewing area so I have to pick up as I go. Company can walk in at any time! ;-) I do however try to keep to one project at a time. Occasionally I will have to fight off burn out by changing and working on a small project for a day or two, but otherwise it's just the one until done. I used to do 5-6 at a time when making Christmas gifts for the entire family all year long, but my DH couldn't keep up with me & thought I wasn't finishing them all. I did, but it was sometimes Christmas Day on the way to deliver it! LOL!! So now I only do one at a time.
