Both the youTube video and the egg carton version of DIY pipe racks are creative. The egg
carton has the advantage of holding the pipes bowl-down, which is a better way to drain
any residual moisture the pipe cleaner might leave (very little I hope). The cardboard box
version has the advantage of being susceptible to all kinds of creative coverings that could
make it look like wood, marble, or avant guard art, with contact paper, wallpaper, etc.
My remedy for pipe overflow has been a basket. The pipes still show, mostly, and can be
stored stem-up. Whatever solves your pipe storage needs and keeps pipes handy. Drawers
and closets are not good. If you see 'em, you'll smoke 'em.
