My mold is nothing close to the nice one in the picture above.
Wow that thing looks nice does'nt it. But if you still want a home made one here is what I use. You will need 2 boards 3/4" by 2 1/2" by 15". More simply put 2 (1 by 3) cut 15" long. Also 2 (1 by 3) cut 5" long. Also a (1 by 6) 16 1/2" long. A (1 by 6) comes 5 1/2" wide, I cut mine to 5" but you can leave it at 5 1/2. Now stand your two 15" boards up on end about 3 1/2 apart and nail one of your 5" long boards on each end flush with the ones standing up. When done flip it over and nail the other 5" board on. You should now have a rectangle that measures 15" by 3 1/2" inside. Now nail that to your 1x6 and you are done. I line mine with freezer paper.
Hope this helps, or that you got one of those nice ones.
