I'm a home wine maker and needed wine racks. There was no solution. The diamond bins were awkward, buying them cost more than the wine. I finally came up with what seems to be an ingenious way to do it. I've been selling the materials list and the complete plans on eBay for almpst a year..over 80 plans have been sold and every single buyer is delighted! On eBay they go for about $9. I can't give them away , but I like this group so I've got a special price of $7.25 for the members. Go to ww.honalee.com/wineRax.htm To see the very special way to build and maybe purchase them.
