buy some project sized bins.
I toss all of the fabric and pattern, cut pieces, in progress blocks and everything specific to that project in a bin. then all of the scissors, pencils, pins, and tools used for all projects in a small bin.
that way when I want to work on a certain project I grab that bin and the tool bin. and I am set to go!!!
a plastic three drawer cart works great for this also!
have fun :D :D :D
