The teddy bear is turning out great. However, I don’t want to do another color for the soles of the feet. So could I just make the pattern and sew the legs together without doing that part? Also, there is no pattern for the tail, because it says in the notes that she added one, but that part is not listed. I have no clue how to make one!
It might be better to makes the soles of the feet in the same color and follow the pattern. That said you can certainly try seaming the legs and see what they look like without the soles.
You can send a message on Ravelry to the project knitter or you could try casting on several sts and knitting a small square then k2tog across the last row, gather and seam. It may take a couple of tries to get the size right.
