The embroidery feet are cut out on the bottom, instead of flat like your "standard" foot. So the fabric will collapse if you're doing straight or regular zig-zag stitch. So, just use them for applique and satin-stitch type stitches, or your stitch quality may not be the best, and your fabric may buckle a little.

I need one too! ;)

I need one!

Thanks so much for this post. Now I feel it is OK to go after that plastic foot [I have never liked] with my pliers. what a good day.

I always use the open toe foot for applique I can see better and get the needle where I want it

I do a lot of applique and I have always used the open toe foot

I have 2 that I purchased on ebay, They make applique so much easier. Much better than the old style feet.

Thanks for the FYI.

I always use a stabilizer on the back of the fabric when doing decorative stitch or applique on machine.

I removed the center of my foot like that with a wire cutter. I also did the same thing to my FMQ foot as suggested by Leah Day. I was really nervous about breaking the foot since they cost so much. I love them now.
