Why not try cutting some felt with your dies. The Tonic Studios verso dies are perfect for this as you can use the outline dies to cut your felt. I hope this gives you some ideas.
Have a lovely day
I had a bit of a brainwave when using the vinyl this time. The vinyl has an adhesive heat activated backing and then on top of the flock there is a thick layer of heat safe clear plastic which you iron on top of ( it is really intended to be used in an industrial heat press) In the past I have either cut through the layers with a die cutting machine that has a metal shim, or have die cut it on the reverse, then it will cut the vinyl but usually not completely through the thick top layer, or just run it through my machine loads and loads of times to achieve a cut. I wanted to use my Tonic Tangerine machine, and I didn't want to cut the die back to front. It finally dawned on me I could cut a square of the vinyl to the size I needed, then remove the thick plastic top layer before die cutting, then put the plastic back on top of my diecut to iron it to the fabric. It was so easy and worked a treat. It cut perfectly first time.
