I originally was selling my Print Drying Racks on my eBay shop but have no added them to my ETSY shop. I've also improved the design.
Originally I "copied" what others were doing and used wire to hold the glass ball in place, like this:
Finding the wires liable to move and jam the glass balls, I went for a long walk and came up with the thought of doing this instead:
I've replaced the wire with thin MDF which I have has laser cut with one rounded corner so make sure no fingers get damaged with a sharp MDF corner.
These have been selling very well, even with a sale to a group of schools for their art departments.
You can find out more here, and buy them from my ETSY shop here.
