Okay...So I up-cycled a couple cardboard boxes by cutting out the several of the same letter and stacking them together/layering them up. worked great AND not such a pain in the butt as the above...(12 inch letters)
How to make cardboard letters and wrap them in yarn. Ahhh, use double-sided tape in the tricky parts. Would have been useful as I struggled thru the M in our family room. Better idea than whipping out the glue gun!
