All I did was get a bunch of frames from a junk store. ( I very rarely buy frames new anymore- thrift stores always have a ton that just need a little spray paint loving) I took the glass out and spray painted them all green. Next, I made transparencies of a bunch of mixmatched letters off of Word. (You know us teachers and our love/hate relationship with transparencies.)
A few nails and a little double stick tape and you are done!
A little while after I did this- cricuts and vinyl became all the rage, but as we have established- I'm cheap and not changing this, but vinyl would look great too!
