Briar is a sweet little bunny to knit up and love.
This pattern is knit in the round in separate pieces and seamed together at the end.
While matching gauge isn't terribly important, I suggest using a needle at least 2 sizes smaller than recommended for your yarn choice to give you a firmer fabric that will not allow the stuffing to escape.
The sample was worked Cleckheaton Perfect Day and stuffed with wool roving. A substitute yarn is shown below.
