I do mine this way as well. I make the pieces different lengths. I don't really measure, just use what I have. What are the odds that all the pieces would end up being the same? That way you don't have to worry. I have an empty paper towel roll that I wrap left over bindings from other quilts and just piece together until I have enough for a scrappy look.
