You know when people running for office put signs up on those wire frames they stick in the ground? Those signs are made of corrugated plastic. After elections are over, I stop and collect those signs, wash them in my bathtub then cut them to 7" by 10" rectangles. They are my 'comic boards' - I have made hundreds of them over the years to wrap all my fabrics....cottons, silks, wools, etc. I feel everything looks its neatest when wrapped and stored vertically on my shelving systems. Everything is sorted by color from lightest to darkest. It makes me happy when friends come by and say they want to 'go shopping' in my quilting store~
