I was doing two swaps...one that was for post-it note holders and the other that was for anything altered...so I just made more post-it note holders.
I think this was the easiest thing I have ever put together. Basically you just mod podge your chipboard coasters, lay your cardstock on over it and allow it to dry. I then cut them out with a craft knife and do the process again on the other side. Being sure that I put the chipboard coasters between some heavy books to keep them flat. After they are done drying and they are cut out I use the little binder clips, and put the same DP on the little black parts of the clip and adhere them with the glue gun. Add some embellishments, primas or ribbon and I'm done. EASY!
