It didn't work for me on my carpet either.
:(

There are lots of different kinds of this non slip "stuff". If one type doesn't work, try another one. Some seem more "sticky" than others. It even comes in colors. I have a bright yellow one. I love this so much I bought a really huge piece from Amazon. It is under throw rugs, small pieces in the kitchen for under cutting boards, opening jars, under cloth table covers and under my foot pedals. I'm probably forgetting other areas that I use it for.

I use the hook side of hook and loop tape if you have carpet. Get the sticky kind, works great for me.

Great idea. Thanks so much. Mine moves all over the place.

I have that shelf lining material and it works well to keep my foot pedal under control, even on carpeting.

Yep, that's what I use under mine also, works great!! You can get it at discount stores too, I think it is used to stop rugs from moving on the floors.

I just got big piece of Velcro, and used the scratchy or hook part, attached it to the bottom of the foot-feed and it never moves!

Velcro has worked for me for years. I stuck it on the bottom of the pedals for both of my machines and neither of them slip on the carpeting. Great stuff!

Try using a good size piece of the loop portion of velcro. Works great for me.

thanks for the tip
