Stand for Princess Gwenevere and the Jewel Riders Dolls?

[Duenia]

I'd love to get some stands to help them stay up instead of having them sitting. A couple of them come with a comb that's also a stand but since the surface they're on is slightly slanted and the combs aren't flat they fall forward. They have the hole in the feet so I'd prefer to use something like that instead of the ones that wrap around the waist. I can't find much online so I have no idea what they would fit. Anyone managed to find some that fit them before?
