..acrylic templates are wonderful! Beats cardboard or sheet plastics "homemade" kind any day....for slippage use whatever works---- sandpaper discs, glue, etc. and yes, investing in rotating cutting mats is helpful....I just bought fiskar 8" for cutting hexies(acrylic template, of course!)...and smaller sized rotary cutter for curves helps too. Just a thought, though, if you buy unmarked, on some shapes you may want to score in the straight of grain line.....like HST, etc. have fun not frustration!
