Coffee mug rack 1

That's Cool! We could  probably use one of those here with all of the coffee mugs we have.

Real simple with a chainsaw and a planer. You have to watch going through the planer as the board edge is uneven so..... be careful and if you do not feel safe doing it, then just use a sand disc very coarse on a grinder but take swaths from it in a sweep motion to keep even. Then finish with regular sanders. The pegs can be metal etc. But make sure you use big ones or your cups won't hang right.
