I keep my cones in 3 drawer closet storage, probably intended for sweaters originally. My one adjustment was to cut cardboard for the left and right edges of the drawer to keep sunlight from affecting colors.
Thank you. I've got built in drawers in the closet where I put my vinyl. My thread is in plastic storage boxes under my sewing table on small rolling tables/shelves. So I really need more boxes that I can fit under the table. I have perfect Sulky storage boxes, they are made for the Sulky brand size. Need something similar for the new thread.
Mine are on wheels. Just measure height of container including wheels before purchase, being sure it will fit beneath your table.
