I have a shallow clear tote that is quite large--I cut strips, iron if needed, then roll the same widths together---I keep adding strips to the roll as I have them.
Other larger scraps are sorted by color and stacked in totes. If I cut squares, then I want a different size!
To make a QUICK strip quilt, I sew the same widths together in a long piece, then start sewing them together--usually alternate wide and narrow. this made a very pretty grab n sew quilt--will try to get a picture of the King size soon as it is quilted.
