Embroidering on Dog Collars?

I use the clamps from hoop tech for that type of work. I keep a sample of nylon webbing work so I can show the customer that the backside will show the top color and bobbin color since I don't wind and run colored bobbins.

you should be able to use the regular needles - probably hoop on a small one - nothing to watch out for - it will depend on the thickness of the material - flexible good luck

I would use clips, like fast frame stuff vs trying to actually hoop them.

fast frames actuall make a special hoop for dog collars and army name tags.
