Process

I followed the instruction of seaming the fabric by sewing machine at the very beginning (got to practice some times before starting this!).

I drew down the line for seaming, and used the pin the keep the fabric fixed not wrinkling throughout the process. Then, I started to work on the sewing machine to seam all the sides. Remaining one side open, I crammed in some bedding cotton. In the end, I hand-sewed the open side.
