Grab it, girl! I never realized I would use a serger until I stayed a week with a friend who had one and "played".......it opens up a whole new world and it's not like you're BUYING something you might not use. If it turns out it's not for you, pass it on.
I serge the cut ends of fabric before I wash it....no ravels, no strings. You can finish things off in a jiffy as many others have already said. I sat down with a pile of old ratty white T-shirts, cut them across the chest, from "pit to pit" then starting at the side seam serged the cut edge to the opposite pit, hung a left, it cut down the side and finished at the same time, hung another left, finished and cut the band off the bottom, hung another left and serged up to the start.....did the same with the back side of the T-shirt. In less than half an hour I had 22 dusting/cleaning rags with finished edges that don't roll up when you wash them! I've made cleaning cloths from wash clothes and towels that start to get frayed edges by finishing them with a serger. None of that "terry lint" when I wash them. I can zip up a pair of cotton knit draw string 'jammie pants' I like to lounge in around the house in about 30 minutes from yardage to pants. I can whip up boxer shorts for the boys in about 45 minutes a pair....I learned the "quick elastic trick" in that class. If you've ever made stuffed animals or pet toys sergers are the bomb. the seams are very sturdy and won't pull apart. The more you use it, the more you will use it.
The one thing I would highly recommend is take an intro class. I learned so much more than I didn't even know I didn't know by just using the manual for
2 years. I took it at the Viking dealer, $25, and there were quite a few people there with sergers of "non Viking" brands. The instructor didn't mind, they all
*essentially* work the same. Check your surrounding dealers and see what you can find, it's worth the time and $$ IMO.
Threading is a snap if you take the time to learn......put a different color thread on each spool and open the manual. Thread it in the *exact* order the manual tells you.....serge a 6" sample, cut the thread then pull all the thread out and do it again.....six times. The different colors helps the beginner not get confused with "where am I?" That's what the teacher had the people in the class do that had trouble threading their machines (and also us old timers, a few times, just to prove we COULD thread it) and somewhere between the fourth to sixth time they were threading those babies up without even glancing at the manual. It's OK to tie off the threads to pull them through, but if you have a snapped thread it's frustrating to figure out threading in the middle of a project. Rule number ONE: learn to thread that thing before you start sewing!! Then also, when you are learning to adjust tension and such the different colors of thread will tell you what each looper is doing. Makes it easier to learn what that machine does and troubleshoot your mistakes.
After you played with it for awhile you'll wonder why you ever put off getting one. Sergers are totally kewl! This gift is a sign from the Goddess of Sergers......go for it!!
