So excited. I am getting a Janome MC4900QC (joint birthday and Christmas present). What I would like to know before I invest in additional expenditure is, does the Convertible Free Motion Quilting Foot Set and special bobbin case really make a difference? Using the standard accessories that came with it, I gave up on free motion work using my Janome 6125QC, it was just too difficult to get the stitches even. I would love to hear if anyone else with my stitch co-ordination problem has found this attachment an asset or not.
