The Nature Of Robertson: November 2020
In this case, the purple floats are in front because you originally knit the work that way, with the pink yarn behind the purple in the catchment column. Since you need to relatch the pink, which is behind at this point, you must carefully reach behind each purple loop in turn, to find the correct pink ladder-rung to hook up next. As luck has it, the purple top of the ladderback basically does not show, not even when the fabric is stretched. The below illustration shows the final result, as seen from the back face of the fabric. The idea here is to unhook the catchment column, thus releasing the floats parked on the fabric face. You are now ready to fasten the top of the ladderback to the back face of the fabric. Note how, within the dropped column, the purple loops are in front. Stated otherwise, there is very, very little slack knit into the catchment column, because the slipped purple yarn does not, in any practical sense, "take up room" between the catchment-column stitches and its neighbors. Like the traditional sewing method, this new way is still done with a length of yarn pulled through the loops, but the "stitches" are real knitting stitches (knit and purl) not sewing stitches, and the work is done only with knitting needles--you can leave the tapestry needle in the cross-stitch kit, where it belongs.
