How is a pinner cap attached on a colonial period doll?

I sew doll clothes for american girl dolls and the like, and want to make some pinner caps for felicity and elizabeth (or any doll) How does american girl doll company have girls attach the pinner caps? Historically accurate is to use a hat pin, but I'm not going to do that. I thought a little hair clip would work well. Thanks!

How is a pinner cap attached on a colonial period doll?

Hi- I just found this site. I also design/make doll clothing (many for AG dolls). When I make a Pinner cap, I sew a very small "loop"--tiny, at both the front (underside) and back (underside).

I then insert a hairpin in one or both loops and 'bury' into the doll's hair. So far, it seems to be working just fine as I've not heard otherwise from customers.

Hope this helps!
