I start with a pattern that I want to make and buy fabric for that pattern. Sometimes the pattern calls for a specific fabric line and because I want that look, I buy the new line. If it doesn't call for a fabric line, I look for the fabric I want at the best price whether it is at the LQS or online. I don't have much stash as a result of the way I buy and I am happy with that. I usually give pieces of fabric I decide not to use, or fabric left over to my daughter-in-law. I know I am in the minority or even a rarity, but it works for me.
