 Set the KC knob to NL, cut and unthread the contrast yarn and knit a few rows of the main yarn (KH910 manual, p.43).
 Binding off is described on page 22 or pages 111-114 of the KH910 manual.

+## Lace
+
+General instructions for lace can be found in your Brother manual. For example page 91 in the [KH910 manual](http://mkmanuals.com/brother-kh910-user-guide.html), and page 100 in the [KH930/KH940 manual](https://mkmanuals.com/brother-kh930-and-kh940-user-guide.html).
+
+To knit lace using AYAB, cast on and knit an inch or two of stockinette, and park the main carriage on the right extension rail, with the yarn in it as usual. The role of the K carriage is to do two rows of stockinette after the lace carriage has moved the stitches around. It remains set to NL, with no buttons pushed in.
+
+Start with the lace carriage on the left rail, outside the turn mark. Set the slider on the lace carriage to N.
+
+Open a lace-suitable pattern in AYAB, such as `10.35.png` in the `kh910` folder of the included patterns:
+
+![10.35.png](img/lace/10.35.png){: style="width:50px;height:150px;image-rendering:crisp-edges;display:block;margin:auto"}
+
+Make sure that **Knit Side Image** is unchecked: lace patterns do not work as expected when mirrored.
+
+The other settings are all default: **Single Bed**, 2 colors, start at row 1, center alignment, you’ll usually need **Infinite repeat**.
+
+Note that AYAB does not automatically repeat the pattern horizontally as Brother electronics do, so you may want to use the **Image Actions** > **Repeat** menu item if you are knitting on more needles than the pattern is wide.
+
+Using the lace carriage and starting from the left, go through the usual AYAB starting sequence:
+
+1. Click Knit in the software.
+1. Move the lace carriage over the left turn mark and wait for the beep.
+1. Continue across, it will select needles according to row 1 of the pattern and beep on the right.
+1. Return across to the left. Are there any needles selected? If yes, go over to the right again, and back. Are there any needles selected?
+1. When you’re on the left with no needles selected, abandon the lace carriage on the left extension rail and knit two rows with the main carriage (usually two rows, can be more). Notice that there are no beeps, AYAB ignores the main carriage in this case.
+1. Repeat: pass the Lace carriage across and back until nothing is selected and it’s on the left, then two rows with the main carriage.
+
+Get into a steady rhythm; not too fast. It will beep at the end of each lace-carriage row.
+
+Lace works best with the bed sitting flat. If your machine is up on the ribber brackets, let the lace knitting hang over the front of the ribber, not down between the beds.
