We have some Polar Notions cards and have folded several projects on them, but you don't really know how much fabric you have by looking at them.
We recently have been folding our cuts that are a yard and up around a 6.5" ruler (perpendicular to the "bolt fold," then in half longwise. Half yards are folded parallel to the selvedge edge, then again same direction, then in half longwise. It looks just like the yard folds, but smaller and distinguishable. FQ are folded parallel to the long edge twice, then ends to the middle, then last fold in the middle. Again, this is distinguishable from the other cuts. Scraps go in a tote bin.
After everything is folded it will fit on any shelf that is at least 12" deep since the yardage is 11". You can use a bookcase, china cabinet, barrister bookcase, or any type of shelving unit to stack everything neatly. Bed Bath & Beyond had a unit on sale recently for $189 that was perfect, but I can't find it online. I wanted to buy it, but haven't cleaned out the spot where it would sit. I hope they still have it.
I hope you get it all organized the way you want it.
