Hello, and welcome from Missouri! I have cousins who have moved to LV from Wisconsin. It has been years since I have been there.
I have found really good bargains at Estate Sales as well. Someone's stash can go for next to nothing by heirs who are not interested in sewing! Good machines are available that way as well. Thrift stores are another good source. Hobby Lobby has coupons as well as Hancocks. Get to know the people at a local quilt shop so you get their flyers for sales and classes. Quilters LOVE to help other quilters!
