What you will need:
- Car seat cushion
- 3 strips of fabric about 19 inches by 5 inches
- 1 1/4 yard of 1 inch FOE or 1 yard of extra wide double fold bias tape
- thread, sewing machine, pins, scissors, etc.
Next, open the fabric that you have just sewn onto the cushion so that the side piece you just attached is right side up. Baste this side piece to the edging of the cushion.Lay the remaining piece of fabric on the middle fabric and pin in place. Again, following the existing seam, sew the last side piece to the cushion. And, again, leaving between 1/2 and 1/4 of an inch unsewn at the bottom of the cushion, or the part that goes on the front of the car seat.
Again, open the fabric you have just sewn so that the side piece is right side up, and baste to the edging of the cushion.Sew the cover fabric to the cushion at the top end, or the end that goes at the back of the car seat, trim.
Fold the fabric under on the bottom, or the part of the cushion that goes on the front of the car seat. Do a blind stitch to secure this fabric, since this part will be visible. (I don't have a photo of this because I didn't realize it would be visible until I put it all back together... oops. So, you can see a blanket stitch on mine in the front of the cushion.)
Finally, sew the FOE or bias tape over the sides of the cushion, and TA DA!
