I think I know what you mean! I purchased four of them...I hung them four abreast in my art-room closet that also is without doors!...and I store my knitted sweaters
in them! But what a neat idea...using them to store
your stash yarn!
The key to strength...the hangers and top framework. Mine have two hangers per garment bag...with a square steel frame at the top.
I can post a photo if anyone is interested.
