We just got a an eCraft cutter on ebay with the express purpose to cut felt. I saw it cut fabric on youtube videos. After importing SVG files and ironing freezer paper onto the felt we found it really needed card stock underneath to fully stabilize. I set it off to make a bunch of small pieces and it went on it's way cutting the paper. Unfortunately there was no evidence of the blade penetrating the felt at all. We set blade pressure up to 8 and set multi cut as high as 5. I even tried removing the blade cover which caused it to tear paper and make a hole in the fabric.
Doing web searches for cutting felt with this machine gives mixed results. I'd like to see this work but if it won't I don't want to waste a lot of time. Any help?
