"One tip I have is to always sew your seams that have more length on one side that the other; sew with the fuller seam on the bottom. For example your sleeve cap would be on bottom where the feed dogs are. Unless you have a walking foot the bottom piece of fabric will be drawn up more than the top.
I keep a large sticky roller in my sewing room. It has a handle like a broom or mop. I roll it over my carpet when I am finished with a project for the day. This way I do not have to get out the vacuum every time. It picks up all those little threads that are so hard to pick up and the vacuum sometimes don't pick up. I am a pretty messy sewer. I drop threads around and miss the trash can A LOT!"
