This is one of my most valued knitting techniques. When knitting a flat piece, eliminate those bumps on the edges by slipping the first stitch of every row.
Doing this stretches out the would-be bump across two rows, giving the piece a cleaner edge.
- On the first row slip the first stitch (either as if to purl or knit) and continue to the end of the row.
- Then turn your work to begin the next row. When you turn your work, the slipped stitch becomes the end of the row, so it is knitted like the other stitches.
I didn’t make this a habit until recently, but now I do it for anything that has an edge of all knit or all purl stitches.
Let me know if you have questions!
