Last night I completed 2 more dresses, 2 more bikers, and 2 pairs of yoga pants to wear with them when the weather cools (pattern info here and here). But knits are super quick to sew up. I just wish I would have whipped these up earlier in the season because I feel like I making things I could probably find on clearance racks. At least it clears my conscious before I start Fall/Winter sewing.
To clarify the specific uses of the Janome Cover Pro I use it for knits because it prevents popping of seams and hems. You can certainly sew knits on a regular machine even without a serger but the Cover Pro finishes clothing much like RTW. Cover stitch machines don't cut and can be purchased with 3, 4, 5 thread options. I do not recommend the serger/cover stitch combo because when I went to my demonstration class the teacher struggled for 10 minutes converting the machine. When sewing in mass production mode I need to alternate between the machines freely. Pattern Review has a pages of info on the Janome Cover Pro 1000. If you are registered (I recommend it -it has a been a great source of support and knowledge for me), check out the knowledge base page and you can read through over 371 pages of question and comments about this specific machine.
