The last step is to stuff the pillow and seal the end with the same process of seam tape and heat.
Ta Da, you have a pillow!!! I added a satin bow to match my bedding. I think I even surprised myself that this worked so well.
The only tip I have is to be sure you check the bond on your seams before moving on to the next side. I found this to be a great bond that is holding the seams very well.
