I've just posted asking for suggestions for patterns, as I'm trying to decide what quilt I might make for my Mum, before I go fabric shopping at a show tomorrow. Supposing I don't find a pattern, and I just look for 3 fabrics in the colours I want. How much fabric should I buy to make a 60in square quilt? Now I know that's a "how long is a piece of string" question, as it depends on the balance between the colours in the design I eventually choose, and the amount of waste, but, assuming I end up with a pattern that uses similar amounts of each fabric, any rule of thumb guidance as to how much I should buy? I'm asking because otherwise I'll probably get far too much "to be on the safe side" - and I've got lots of other things on my shopping list, so would like to have some money left!
