Great question!! I just bought a new "scrap" plastic tub yesterday. I plan to keep anything over an inch that way using two 1/4" seems I'll have 1/2" left. There are a ton of quilts that need pieces that small. I also really like the projects people on here have done using leftover selvege pieces. Then just use my own judgement on how big to go. I think I'll get a larger tub for the bigger pieces just so I can keep them seperate. My daughter has used all empty tubs around her to store her stuff while she's on deployment so naturally Mom has to go buy more. Our daughter joining the Navy has cost us a fortune! ;-)
