I like it and always use it when FMQ with my Bernina. I tape it down to make sure it doesn't move. I rinse it occasionally and consider it a good purchase.

I love mine. Tried to FMQ without it for just a small project and had to stop and go get it. My DSM sits on a table, not set into a sewing table, so, may be that's why it seems so valuable to me.

Well, I have one but sewed it to my quilt several times, even though I used masking tape to hold it down.
