I have had to buy a bolt at the wholesaler and last year it was $1.35 per yard on sale. Now it is much higher but still less than $3. Can only get it by the bolt which is around 15 yards or 5 yard flat folds.
So it is totally possible to get LQS fabric from major manufacturers at these prices and make a profit or end up with big pieces leftover. Or be given lots of fabric from an estate or someone moving.
