Studded leather what am I missing?

[Sherm]

I look at the wiki and other sites and see that skins and pelts should be interchangeable. Which is good since all I can find are skins and the recipes say pelts. However, they aren't working

http://wiki.project1999.org/Skill_Tailoring

Shows MQ bear/wolf/cat pelt + studs + pattern. I try this and get "you cannot combine these items in this container type. I get this in both my large sewing kit and the loom. Is this maybe a bug, or am I doing something wrong?

Nevermind I figured it out. Thanks
