WHAT IS IT?
Slash front pockets, or one-quarter top pockets, have a cutout on the surface of the garment and a pocket bag filling in that cutout and finishing the shape of the garment piece. A great example of this type of pockets is found on jeans; the front pockets are nearly always slash pockets. The opening can be curved (like jeans pockets), a straight line running diagonally at the hip or a right angle. These pockets are comfortable to put your hands in and easy to access. The pocket bag can be self fabric or a contrast fabric with a facing at the opening.

WHEN DO YOU USE IT?
Slash pockets are frequently used on the front of trousers and casual pants. I like to use them on dresses and skirts, as well, as they’re easy to sew and add practicality to my garments.
Tips + Notes
If your pattern doesn’t have pockets, but you want them, it’s an easy add-on. Borrow the pattern piece from another pattern, trace the opening onto your skirt or trouser front and add the pocket. Reshape the part of the pocket that fills the cutout so it matches your original pattern.
HOW TO SEW A SLASH POCKET
If there are facings (page link), sew the facings to the pocket bag. Finish the edges of the facings, place them right side up on the right side of the pocket bag and edgestitch (page link) along the finished edges. Baste (page link) the raw edges of the facings to the pocket bag and treat it as one piece from this point forward.
Pin the pocket bag to the garment opening. You may want to add stay tape (page link) to the pocket opening so it doesn’t stretch over time. Sew the pocket bag to the garment, trim and clip (page link) the seam allowances.
Understitch (page link) on the pocket bag side of the seam, and press the pocket bag to the inside of the garment.
Fold the pocket bag along the fold line so that the lower edge of the pocket matches and the pocket bag fills in the cutout. Sew the lower edge of the pocket bag and finish the seam. This is a good place for a French seam (page link) as it finishes the edge nicely.
Baste the pocket to the garment along the top edge and the side edge. Continue sewing the garment, treating the front and pocket as one piece.
