Because bamboo skewers already have a point, all you have to do is run your hands over the skewers and check for any remaining rough spots and smooth them out.
Slip a bead on the opposite end of each “needle.” This isn’t necessary but does make them look more like knitting needles. If yours aren’t perfectly snug, add a bit of glue and allow to dry.
The first couple of rows of knitting will allow you to find all the remaining rough spots, so knit with your sandpaper nearby.
Once you work out all the kinks they’re actually just like knitting with regular bamboo needles, and a lot cheaper.
