Sorry in advance for probably stupid questions
...
I've made a number of bags now with a variety of cottons. I've used interfacing to strengthen them, but now am thinking I'd like to try using heavier cotton (I think it's called duck cloth but I can only seem to find it in white or cream, so maybe I've got the wrong term?) like canvas bags are made of. What should I be looking for and anyone know of a good (and cheap!) shop (online or real) for it?
Also, I would like to give oil cloth (again, think I mean oil cloth? basically I want a wipeable cloth) a go, but have never used it, so not sure how to go about sewing with it? Does it just tear? Is there a special thread I need to use with it?
TIA :)
