WooHoo!!! :D:D:D
http://emblibrary.com/ has a big section of tutorials. It explains about which stabilizers to use, and how to hoop different projects, lots of other information.
I would avoid coffee filters, dryer sheets may work on some things... The sucess of a wrinkle free embroidered project depends on the stabilizer. Walmart sells washaway, cutaway and tear away, as well as Joann's if you are looking for good deals. I buy it off of the bolt and it can be cheaper than the packages.
