This is a very simple bunny to make, knit flat and using not many materials. It’s really only rows of knit or purl. Don’t let the provisional cast-on deter you, as an alternative it’s easy enough to pick up stitches from the bottom row using a smaller size knitting needle.
The pattern instructions create a rabbit that is about 8” high and 4” wide. You can make it larger or smaller simply by adjusting the amount of stitches cast on and the rows of garter stitch for the body, stocking stitch for the face, legs, etc. You can also use finer yarn and smaller needles, the gauge doesn’t matter.
