Forest is one of my favorite colors.
Dark Green with a bit of yellow in it.
Hunter Green has a bit of blue in it.
Invisible zippers by the yard are the least expensive way to purchase zippers for pillows. I normally sew in the tape first & then put on the pull. Sew the 3 sides up to complete the pillow. I have videos above.
By sewing the tape in, then cutting off, you won't have any waste.
