I made a bathing suit years ago, but I found the fabric to be thinner and not of great quality. Are there online sites to get better quality fabric? And is price the only way to measure quality?

    Helen - July 16, 2021

    Well it’s a bit tricky to buy swim fabric online. No the price is not the only way to measure quality. I’d check the real user reviews to see what others say about the fabric.
