Step One

Cut bias binding, 2” wide, and stitch end to end, at a 45-degree angle. Make 2 yards.

Cut two rectangles 3 ½” x 5 ¼” and two rectangles that are 3 ½” x 2 ½” from the cover fabric.

Cut two pieces of interfacing that are 3 ½” x 5 ¼”.

Step Two

Remove the cover from the booster seat. Use a seam ripper to take it apart.

Use the pieces of the seat cover for patterns. (Note: Because the cotton cover you are making will not have the capability to stretch, we will attach hook/loop fasteners to the portion that wraps around to the back of the arm rests.)

Step Three

Cut the seat cover and lining pieces into 24”x 30” pieces. Cut a piece of foam about the same size as the pieces.

Spray the wrong side of the lining piece and smooth onto the foam. Turn it over, and apply the cover piece in the same manner.

Pin the layers together using safety pins, and use a walking foot to stitch the layers together in lines that are 3” apart.

Step Four

After the fabric is quilted, pin the pattern pieces to the fabric as shown, and cut out, adding 1” to the lower edges of the cover, as pictured.

Zig zag around all the edges of the pattern pieces, then use a straight stitch to stitch around the edges again, ¼” from the zig-zag edges.

With right sides facing, pin the side panels in place, and stitch about 3/8” from edges.

Step Five

Fold the binding in half, lengthwise, and press so raw edges are together. Pin to the lining side of the cover. Stitch a scarce ¼” from the raw edges, adjusting the binding to the curves as you go, and opening the seams as you stitch across them. Do not bind the ends of the cover that will wrap around the arm-rest portion of the booster chair. They will be the sections that will have hook and loop fastener adhered.

Fold the binding over to the right side of the cover, and stitch close to edge.

Step Six

Retrieve the rectangles from Step 2, and fuse the interfacing to the two larger rectangles, following manufacturer’s instructions.

With right sides together, stitch the rectangles to the two unbound ends of the back section of the main section of the cover (not the side panels). Stitch ¼” from the edge and press toward the seam allowance.

Step Seven

Press the long edge of the rectangle up ¼”. Fold the rectangle, right sides together, with the folded edges even, and stitch across the ends. Clip the corner.

Turn the rectangle right sides out and stitch close to the folded edge.

Step Eight

Repeat steps 14-16 to cover the ends of the side panels in the same manner.

Step Nine

Cut the pieces of hook/loop fastener to fit the ends of the back tabs. Place the hook sections on the lining side of the tabs and follow manufacturer’s directions to adhere. Note: Use two layers of pressing cloth to protect your fabric so the iron won’t scorch the fabric. Watch the temperature, and use plenty of steam.

Step Ten

The loop portion will go on the right side of the side section of the cover.

Push the front of the seat into the cover, then wrap the side and back ends around the arm rests firmly.
