I have had a Brother KH551 Knitter and Ribber for about 45 years. I have made beautiful sweaters, dresses, suits and coats on the KH551. I have not mastered the making of multicolor knit fabric because of the carry over challenge. When the carryover is in excess of 6 stitches for a second color the carryover is in danger of being snagged. How does one secure the 2nd color in long carryovers on a knitting machine?
By carryover I'm presuming that you mean floats, the strands of wool that are carried across the back. You can, after a few rows, pick them up and put them onto a needle before you knit the next row. This will catch them up into a v shape. You can also use the main bed and the ribber together and do double bed Fairisle were all the floats are knitted in has you do it.
I learnt to hook the floats over the selected needle(s) for the next row so they get woven in when that row is knitted. Floats over many stitches can safely hooked up on to several needles so that none float over more than four needles. Hope that might help with your problem?
what am I doing wrong as when I place the float over the above stitch it usually shows on the right side of the garment. Help needed please,
