It is very easy to make horizontal button holes for small buttons when knitting projects using garter carriages. This blog is a text version of the video posted on the same subject.
First, decide the position of the button holes. Pick two stitches (in my demo, I decided to pick two sets of two stitches where I knew the machine needles, not the carriage’s, would knit). Move the left stitch out of these two to the stitch to the left of it and the right stitch to the right of it. Push the freed needles back to B position.
Knit one row with your usual pattern. The needles that were empty, now have yarn hooked on them (no stitch formed). Using a double eyelet tool, take the yarn off one hook, twist it, and then put back into a needle. You just formed a loop. Do it for the remainin needles in the button hole.
Continue to knit as usual.
