There was a discussion about 505 spray, on this site several years back. There was a link to a research project that stated that 505 was considered the safest spray to be used on 'museum quality' quilts. It 'aged' the best, for want of a better term and never affected the fabrics. My quilts will never be museum quality but if it's good enough for them, it's certainly good enough for me. Sorry I can't remember who started the thread or the link to the research. But I definitely remember reading that statement because I passed it on to several quilting friends.

I love the product. Hope it stays on the market.

It's nice to hear from companies when you have a question about their products.

Confused here. Isn't the purpose of 505 simply to hold the batting, front and back of quilt in place just while it is being quilted? If you follow the directions on the batting label it will tell you how far apart your quilting lines should be to prevent shifting of the layers so, if you follow their instructions, why would you have to worry if the spray washed out. If no hard, dried particles remain and it doesn't affect the fabrics, as others have attested, why not use it or am I not understanding the problem?

Some people don't like the idea of extra chemicals in their bedding ... although, in fairness, 505 spray doesn't seem to be any more harmful once applied than whatever chemicals were used to dye or print the fabric and those also don't wash out.

i will continue to spray baste. If it weren't for basting spray I would not be quilting. I don't have the patience for pinning or thread basting.

I, too, use it every time to baste my quilts. I have left them sit for months. I have snuggle quilts we have used almost daily during the last four winter months. They get washed often. No problems with any of them. I would not give it up.

We know it's there now:)

I too have used the 505 spray. I made my grandson, daughter-in-law and son, also made my daughter a quilt. Never has anyone of them complained about any hard particles in their quilts. I made them 5 and 6 yrs ago. I love the spray. It is a miracle worker and time saver.

Thanks for posting this info! I think if I was making an "heirloom" quilt, I'd avoid using it.
