I got a serger for Christmas! It is a Viking Huskeylock 905; basic without a computer. The clerk said it could everything the next one up could do, but without a computer. There are charts in the owners manual. I plan to sign up for classes, because I have never used one. What books do you all recommend? Any special warnings or tips? I have purchased Serger Secrets, a Rodale book, but it seems to be talking to people who already know what they are doing. Anu suggestions will be welcome.
