I save money by not having a "stash". I have found that the colors that I have on hand usually do not match newer fabric colors. Guaranteed that the green that I have will not go with the fabric I buy for a new quit! There for I buy all the fabric to make a quilt pattern! Can seem expensive all at once but I do not have "extra" fabric setting around.
Also shop hobby Lobby is there is pone by you. Nice fabric always on sale at 30% off.
