Here is what you will need:
Scrap piece of 1x1
Wood Drill Bits (size will vary on the spoon's handle size)
Hot Glue or Strong Glue
Screws (at least 2 inch length)
Start by measuring the coffee mugs.
Most of ours mugs are around 3 inches, although we did have a few at 4 inches.
Next measure the wall, decide how long and how many mug racks you want to make.
(We ending up with about 19 inches in length and started with 3 racks but ended with 4.)
Now take the 1x1 measure and cut to the length. (4 at 19 inches)
Now mark where each spoon will go. (This took a little bit of math, a little guess work.....you know how that goes.) We took in consideration that a couple of the mugs were four inches, and thought we should also think about handles too, so we spaced the spoons 5 inches apart. The spacing worked out well.
We made a mark 2 inches in.
Fill the holes with hot glue.
We found it easier to make... kind of ...a cap on top with he hot glue, then flip it over and fill the hole the rest of the way up.
(You can use a stronger glue, hot glue dries faster, so there is less of it running out of the hole. At first we were not sure if the spoon, wood and hot glue would bond together. We took a piece of sand paper and ran it over the part of the spoon that would be inserted into the hole. We thought the ruff surface would help the glue stick better. I don't know if it really did anything or not, the spoons do not move at all. It could just be that there is so much glue inside each hole.)
Once the glue is dry, you can paint wood (like we did) or mount the racks on your wall as is. (Make sure you use enough screws to support the weight of the coffee mugs.)
Add your coffee mugs and you are all set.
