I use the Sulky KK2000 on small quilts and love it. I'm never going back to anything that has to be removed as I sew. There is no odor. The can says it's safe for the planet - no CFC's or HCFC's, and the can is recyclable. It seems much safer than hair spray. I have not used it on a bigger quilt yet. The only drawback is that it breaks down after a few days. That's also a plus, if getting finished with the quilting promptly is not an issue. I have not had problems with puckers or wrinkles in the quilts I've used it on, and the only stickiness is where it belongs. It works fine on W&N. It's a great product, but if it were not for hefty discounts with the store coupons, I'd never have considered it.
