What you need is a bunch of scraps, cutting directions will be posted shortly, but start gathering about 12 lights 5 darks and 3 of the same med. most are going to be one inch cuts, the darks are going to be up to 3 1/2 wide.
The mystery will be posted and at any time you can go back and finish it if you don't that day. The mystery is only for the day, after that it is no longer a mystery. But you can still do it. Any time, the instructions will be there for anyone that wants to do it. There are going to be some that are busy that day or whatever (some want to see what they are making before they make it.)
