i embroidered a peacock on the back of a jacket and had to hoop it 4 times and used metallic thread and the only way i could keep from breaking every little bit was when using metallic thread you have to have the spool laying down in a box or something like that so that it can roll off the spool,,,it the spool is sitting straight up it comes off twisted and will knot and break,,,i also sprayed the thread with silicone,,which can be found at your local wal mart,,,,also use a bigger eyed needle,,,i hope this helps
