Best way to cut Thinline material?

I got a western Thinline pad for a great price. I have a dressage pad with pockets I would like to cut the Thinline to fit. Now, I have trimmed Thinline hoof pads to fit into hoof boots, but I need advice on the neatest way to cut the material. Scissors just don’t cut it; I mean yes they do cut it but very jaggedly. I’m not great cutting straight lines with an exacto knife, even when the lines are drawn on. Plus I’d like to use the excess for Mattes pad shims, so not wasting any Thinline is preferable.

Help!

I have no proof of this, but I bet a rotary cutter (the kind used by sewers) would work really well.

I use kitchen shears and they work just fine. Maybe the lines are a bit jagged, but I don’t think that hurts anything. Glad to hear that someone else cuts up thinline pads to use as shims!

Kitchen shears worked great for me - no jaggedness on mine - just cut slowly and carefully.

I used a utility knife.

I’d contemplated a rotary cutter, too. Winding Down, I am just anal retentive enough that the thought of poorly finished edging makes me twitchy :lol:

I use leather cutting scissors. The other tool that works is for plastic cutting.
