So I have watched this video on youtube several times and I think that these feet are really cool but I don't know if anyone has ever really used them. It states that they can fit on any sewing machine they are called http://www.creativefeet.com/ it looks very interesting.
The feet look interesting. I'm not sure how the prices compare with feet that are made specifically for the machine. It might be worth comparing if someone is interested in buying specialty feet.
I have never heard of Creative feet but they sure do look pretty cool! I really like the Satinedge foot, but I think I would call or email prior to purchasing to ensure they will fit on my specific machine. Thank you so much for sharing this!
