Rowsmith

Tool 1 of 4 · Even Spacer

Increase or decrease evenly.

Tell it how many stitches you have and how many to add or take away. It writes the row, checks the count and draws where each change goes.

Knitting decreases are k2tog. Crochet uses two stitches in the next stitch, or two together.
Layout
Easy groups the longer runs first. Most even spreads them through the row.

How it is worked out

The plain stitches are the stitches that are not used by a change: all of them for M1, one fewer per increase for kfb or two in one stitch, two fewer per decrease for k2tog or two together.

Worked flat there is a gap before the first change, a gap between each two changes and a gap after the last; in the round there is one gap before each change. The plain stitches are shared out over the gaps as evenly as whole stitches allow, so gaps never differ by more than one stitch. When there are at least as many plain stitches as gaps, every gap gets some: a flat row then starts and ends with plain stitches, which keeps the edges tidy for seaming. When there are fewer, some gaps stay empty and those changes are worked side by side, written as one repeat.

Before you start

Place a stitch marker at each change if the row is long, and count your stitches when the row is done. If your pattern says where to put the changes, follow the pattern.

Abbreviations: K = knit; M1 = make one; kfb = knit into the front and back of a stitch; k2tog = knit two together; sc, hdc, dc = single, half double and double crochet (US terms).
