I'm very pleased to introduce Buddy the Boston terrier puppy!
Buddy is my last creation before the Summer break and is now available for adoption here: http://www.ebay.com/itm/182180526003?ss … 1555.l2649
I remember your last puppy, it was a really nice job.
High quality faux fur can be a better choice, depending on the look you need to achieve. I use faux fur a lot for realistic looking dogs, wolves, foxes, raccoons and so on. Mohair doesn't give the same result.
As for the paw pads, I also make it with polymer clay. I have used Apoxie and Fimo, they work really good, an you can also paint them over for realism. I do not put a wire loop. I simply attach the tiny bits with extra strong glue which dries very fast. You just have to trim the fur in the area where the little bit goes, so that it is attached onto the fabric and not on the fur. Apoxie is very strong and doesn't break easily. I think you will have no problem with Sculpey too.
As for the armature, you can make a flexible armature using multiple shafts of galvanized wire. It is a lot cheaper than Locline and works really well.
