Last year we had wardrobes fitted in my sewing room (spare bedroom) and I use a single one with shelves for my sewing resources.
Because I don’t have a lot of space I try to just buy what I need for a project. I often buy pre-cuts rather than yardage so there is often something left.
I have storage boxes that fit the wardrobe shelves and have fat quarters in one. When I finish a project I cut what is left into 5 inch squares as I seem to use these the most. These go into another box. I have another box for long strips 2.5 inches wide for scrappy binding.
I know someone, somewhere, might use the bits I don’t want but as I don’t know that person or of any groups or guilds in my area I ‘donate’ them to the bin!
