I don't remember who was asking and posting and....blah blah blah and even which *home* it was on for us. Anyway...someone had recommended the plastik or something like that putty type of stuff to hold posters. ANYWAY...whew I have this new tape stuff that works GREAT! It's mavalus tape and I purchased it at our local educational supply store, around $3 for a roll. You then sort of fold the tape in thirds and stick. www.mavalus.com
She... I love that tape too. I discovered about mid-year last year and have used it ever since. I need to keep a running stock!
