Do what is right for you. To tell you the truth, I quilt because it makes me happy. I don't care how a quilt will hold years down the road. You could use the most expensive materials and give away a lovely quilt that may end up in a dog's crate (seen it). What matters is that it brings you joy. You may venture into other kinds when you can afford it, but in the mean time don't stop doing it just because it may not hold later. I am not in a situation where I can spend any money, so I am making small quilts. Bought a roll long time ago and stretch it by using little bits at a time.
