how do you attach your arms?

[video567]

i was wondering what methods do you all use to attach your arms to your puppets, do you sew them to the body? use some sort of hinge? a few years ago i bought a hinge looking think was a circle with a stick comming out of it then you puncture the foam with it and attach like a washer on the other side aand it would hold the arms. these last few days i have searched in every craft store in my city and havent seen the same thing again. anyone use something similar and if you do where do you find it?

i found it onthe net they are actually called Plastic Doll Joints, google is my friend. now if i can find them locally I will be happy, michaels, joans, hobbytown, nor hancock fabrics dont carry it. I'll buy them online.
