Stabilizers... for me, have been a trial & error. There are so many offered under various brand names, and so many types. All available in different weights for different uses are water soluble, tear-aways, cut-away, iron-ons, mesh types. It can be confusing! I like the Sulky TearEasy & Sulky Iron-on, Pellon SofStitch cutaway (walmart), and the water soluble type at walmart (don't remember the brand name). One I've recently tried is Hollingsworth Tearaway/washaway, which seems nice, since the stabilizer under the stitches remains to continue support of your design even tho' the excess around the design washes away. Works great, in fact, it is recommended by one of the digitizers on a forum I visit. Check out the Martha Pullen Phorum for a lot of helpful info and advice.
I haven't been able to take lessons locally, but learned a lot through the internet, forums, books, google searchs, and trial & error. There's a lot of free designs offered by a lot of the companies and some of the Yahoo user groups.
I really love using my machine, and have found so many uses for it. I've put designs on t-shirts, fleece throws, baby bibs, towels, embroidered squares for quilts, pillow covers, and today I just finished 5 Christmas stockings with a small design and names on the cuffs. Then, of course, you can make lace, using the water soluble stabilizer. I've made lace angels & ornaments to send with my cards this year. Oh yes... you can do quilt designs also. I posted a photo (in the photo section here) of a baby quilt I made recently, using a sashiko type quilt design on the printed fabric squares.

This is getting longer than I meant to write, but I hope it is of some help. There is so much to learn, and I'm still learning. The only thing is, what do I do next... embroider or quilt?
