I have embroidered designs on a bag consisting of fabric then batting then stabilizer no problem.

not felt, but quilting in the hoop was quite successful. I might be a bit reluctant to try if the felt is very dense, like some of 'industrial' kind.

Just use WSS (water soluable stabilizer) on top to keep your stitches from being buried in the fabric and there shouldn't be a problem.

I love felt . I did all my toilet paper covers on felt and you will become addicted. Kay

I embroidered on the wool felt.thicker than craft felt with no problems. Slow your machine down and it should be fine, I don't know what the thickness was

"Welcome" I haven't tried felt that thick be have embroidered on a fabric block sandwich came out great, it might depend on how dense your design is... Good Luck.. Marian

Welcome to the cute family,I have made a lot of various things with felt, no problems and back with a cotton fabric to protect the stitches. bookmarks, easter bags all great projects. Sandra.

I recently worked on a hot pad project that at first was afraid to try because the whole thing hardly fit under the presser foot. It had 2 layers of fabric, 2 layers of warm and natural and a layer of insulbrite. I embroidered a filled design that had quilting stitches surrounding it, and was so surprised when I has no issues at all!
In the case of the thicker felt, probably the only thing I would wonder about is if there is too much friction on the thread causing shredding. If that turns out to be the case, I think a needle with a larger eye to protect the thread may help.
If you decide to do this, it would be nice to hear how it turned out for you. Judy

I have seen embroidery done on balsa wood so I suspect you would be fine to embroider on the thicker felt. I would assume the settings would be similar. If you google search to embroider balsa wood there are a few good sites with detailed instructions.
