Children`s jumper Polar Bear by Linka Neumann. I chenged the pattern a bit, made it easier for me and simpler to accomplish. I changed the ribbing on the bottom later in the process, because the sweater turned out too long. I decided to mimic a steek and cut off the ribbing and a bit more, secured the cut line with zic zac stitch on my sewing machine and sewed on a yellow elastic band, right sides together. I then turned the band inside and secured it with hand stitches. It turned out quiet good and the seem is really elastic and stretchy.
