Before I had a quarter inch foot,I used a piece of blue painters tape to mark a line on my machine...won't leave residue
I get a telescoping magnet stick from a parts store to sweep across my floor to pick up pins.[saves my back and knees]
Zippered plastic bags from pillow cases and sheet sets make excellent project bags..
I use the bright colored elastic pony-tail holders for making button loops for button instead of making fabric loops...these work on jackets or other clothing or crafts...and purses..
