I just wanted to share my idea for a cheap storage solution. (Maybe it was done before)
2x4, 5/8" wood dowels and a drill with a 5/8 wood bit is all you need.
I have build this for my heat press vinyl.
For a regular sign vinyl I would probably use thicker dowels (10 yard rolls) and I will not use this for a 50 yard rolls of a sign vinyl.
Hope it helps someone with getting their rolls in order
