I got my Coroplast & had my husband cut some 9" x 24" pieces for bolts of fabric & love how it turned out. I probably paid too much, but thought I would start with 2 sheets to see how I liked it. I don't like the possibility of the edges, if sharp, to cut the fabric or my hands. Therefore, I used a high quality acid-free tape on the long edges only. I got 20 pcs. from a sheet @ a cost of about $1 each. Now that I like them so much, I will have to look for a better price per sheet locally, if possible. Thanks for the flute directions OP, it worked well this way.
