You need to use the correct stabilizer for your fabric and stitch density. Printout the Stabilizer Workbook at Floriani under the Solutions tab. It's a great resource no matter what brand you use.

You don't use interfacing for embroidery. You must use a good quality stabilizer.

Bunnylane...check out this website...I have used their 1.8 oz tear-away 12x25 yds (14.99) and love it. http://www.myhobby4less.com/tear-away.aspx

Also make sure your bobbin is in correctly and your using embroidery bobbin thread.
