I decided on the Janome Coverpro coverstitch machine. There is a great support group on Patternreview. There is a four part guide with tips and great information provided by Coverpro owners. There are also several useful videos on youtube.com with helpful hints such as how to remove the fabric without unraveling the hem. I told my hubby that it would revolutionize my sewing. That might be just a little bit of an exaggeration but not much. He said it sounds like I should get one just as long as I charge it on the card that earns his free flights!
I had a busy weekend and haven't been able to actually sew with it yet. I did try it out though since it was threaded and ready to go right out of the box. This sample hem was stitched after removing one of the 3 needles with very few adjustments.
Now I will really enjoy sewing with knits. Any suggestions on mail order sources for nice knit fabrics?
