You get 2 bandanas and I folded them in half, that way when i cut the arm it would all be the same size.
Measure from back of shoulder to front armpit and cut the arms. Sew the trimming of the arm. Fold the top down with enough room to slip your ribbon in. You will do the same for both bandanas
Sew the sides together of the bandanas. As you can see I stitched it twice only because my daughter is mini mini so I had to take it in but no biggie! No need to sew the bottom because the bandanas are already sewn but if it's too long you can :-)
Then Ribbon it up and you're done!
