3-D pockets are a bit fussy to make, but they give lots of extra room and look great too.
- felt (optional)
Make The Pattern:
First make the pattern. Draw a rectangle or square and extend the lines the same amount (shown in red) to form the side and bottom gussets. I extended mine 1 inch on each side.
Next, cut out your pieces. (1.) I used the same fabric for inside and out. Iron on interfacing to the main fabric (or the piece you will use on the outside). I suggest you use felt also. Just pin the felt piece to the interfacing. Then right sides together, (2.) sew the sides and the bottom together. Open the corner (3.) and sew it together (4.) Turn the pocket right side out through the top opening. This is how it (5.) will look.
Push corners of (6.) the lining side in. Fold (7.) sides down and topstitch (8.) with 1/8 in seam allowance along the fold line.
Pin in place, making sure that the sides are upright.
Then fold the gusset down on the pocket, pin and sew just that side as close to the edge of the pocket as possible. Repeat with the other side and then the bottom.
That's it. You just made a nice roomy pocket.
