The Sims 4 Kits - Bite-size packs, big possibilities

I have an issue with the knifty knitting pack, in sims 4. Im trying to start my own store which is another reason why I bought the knifty knitting, to create more stuff to put in my store. The problem is the only thing I can only sell in my store are the poufs and decorations. It will only allow me to sell those, Im frustrated because my sim has the marketable traitand she can't sell the clothes, rugs, plant holders etc. In store at all, which sucks because hand crafted items go for more. Yes I know about plopsy, I don't like it I wanted to use my marketable trait for my store.
