2 contrasting fabrics (fat quarters work perfectly!)
Moon Stitched Ribbon (or any wide ribbon)
To fit someone bigger, just add a little more length to the straps.
Cut out 2 panels of your main fabric, 11″W X 10″L.
Cut out 1 panel of your quilters batting, 11″W x 10″L.
Cut out 2 panels of your contrasting fabric for your belly band, 14″W x 6″L.
Cut out 2 panels for the crotch strap, 3″W x 6.5″L.
Cut out 2 panels for the shoulder straps, 2.5″W x 9″L.
(These can be cut on the fold so that you only make two cuts, see picture below).
Cut 2 strips of ribbon 12″L and 2 strips of ribbon 18″L.
7. Sew along the bottom of one of your shoulder straps and up the side. Do the same for the second piece. Turn right side out and iron flat.
Find the center along the bottom seam. Match up the crotch strap with the center mark, overhanging the fabric by about 1/4″. Pin crotch strap in place.
9. Along the top of your main fabric, measure 1.5″ and place one shoulder strap (velcro face down) and then one 12″ ribbon. (not shown in image – yes, I got all the way to having this sewn together and realized my mistake and had to rip out the top seam! The second picture above shows me placing the shoulder strap and then the ribbon on top of that. Grrr…). Center the ribbon over the shoulder strap piece. Pin in place. Do the same for the other side.
Do the same for the second top ribbon.
This will prevent the buckle from sliding off.
