There are a few things you can do. I keep a tote bin for my different used stabilizers. There are times when you may need to double up on stabilizers, you can hoop a whole sheet and then I use spray (like 505) except that I use the one from Walmarts and I add it to the full sheet, as many layers as I need. There are times where you'll need it on top of a design, like on a towel or even doing fonts, they stand up so much nicer if you float a piece on top of the fabric along with the one in the hoop. I also make garments and sometimes when either sewing or serger I'll need a small amount of stabilizer to hold the edge when doing special hem finishes and this is a great place to use leftovers. The water stab. can also be used to soak FSL in to make it stiffer when you need it to stand up. As you embroider more you'll find a way to cut cost and it won't take you long to figure out areas to use those odds and end pieces. Just like when I'm doing FSL in a project for the kids and I want it to hold up longer and knowing the kids are going to play with I'm not spending a fortune in thread, I up my needle size, slow down my machine, float several pieces of water sol to make it stronger and I use serger thread. It turns out great and I love variegated thread and there are so many varieties in color. There are a lot of ways to save money, I hate to throw away things if I can avoid it, little pieces of fabric that I used to throw away, I now save for emb when It also includes applique.
