I like to make by hand almost all the gifts I give during the holidays. Men are usually the most difficult for me to make successful handmade gifts for! Here are a couple of suggestions:
Duct Tape Wallets
Duct tape wallets are great for guys of all ages. I made them one year, and grandpas, dads and brothers all liked and used them. They were quite a hit, even with the guys you wouldn’t expect.
I used instructions here to make mine. Each wallet takes about 30 minutes to make, but they’re super cheap and fun.
Etch, paint, or otherwise personalize some shot glasses, pilsners, pint glasses, or even coffee mugs. This example by littlecabbage.com.
