Im started playing Morrowind Crafting along with my business mod PC Clothing. I would like to make the clothes i sell in my store, but i have only found about 8-10 blots of cloth after days of playing. The vendors does not restock and i have only made a few piece of common clothing out of what i found. My sewing lvl is 13 and if this is all i get to produce with this skill in the game im pretty disappointed. Anyone know of restocking merchants selling bolts of cloth?

Most Clothier shops sell some, and almost each of the bigger towns has at least one Clothier.
Vivec has a few merchants that are selling them too. You should head to the St. Olms Tailors and Dyers store.

I belive the merchants that are added by MW Crafting should be selling some too. You'll just have to find the correct merchant.
The documents that are included with the MWCrafting download should have some detailed info on this.

I think there are some laying around in Saint Olm's Storage and a vendor in Mournhold that sells some. I doubt he restocks.

The outfitter in Balmora usually has some bolts of cloth. And they should restock every once in a while, too.

What I'd do in your situation is to make my own bolts of cloth though as quickly as I could. The Tribunal Temple in Ald'Ruhn for instance sells marshmerrows, and I am sure you know how common these grow near Sadrith Mora.

there are a few laying around here or there. the easiest ones i think you can get to in vivec are the ones in the storage area in the arena canton.

Keep in mind that it isn't just the bolts of cloth that can be used to make clothes, the folded cloth or cloth squares that you find in many of the outfitters or traders shops, as well as in many houses will work just as well.
