Sew a Drawstring Bag and Plan the Cord Channel

A drawstring bag needs more than a folded top. The channel must be wide enough for the chosen cord, its ends must remain open, and the body seam must not accidentally block the route. Sorting out those three details on a scrap makes the actual bag much less puzzling.

This is a plain, unlined practice bag for an adult's lightweight fabric scraps or similar items. It is not a child's toy, garment, crib accessory or heavy carrying bag. Loose cords create hazards, so keep the finished bag and its drawstring away from young children and moving equipment. Choose another closure when cords do not suit the setting.

See the route before cutting

LearnCreateSew's drawstring lesson describes the casing as a passage for a drawstring. For this exercise, picture two passages: one across the front and another across the back. They open at the sides, allowing one cord to pass through both and bring its ends out together.

Choose a flexible cord and test it inside a folded scrap. The sample must accommodate both the cord and the threading tool without a struggle. If the planned channel is unsuitable, change the dimensions on paper before cutting the panels. Keep the cord uncut until the completed bag can lie fully open for measuring.

Prepare two matching panels

For an original practice layout, cut two stable woven rectangles, each ten inches wide and fourteen inches tall. Use half-inch body seam allowances. The top folds consume two inches of height: first half an inch, then another inch and a half. The nominal finished bag is nine inches wide and eleven and a half inches tall, including its casing. These dimensions describe an illustrative sample, not a commercially tested pattern or a rated storage product.

Finish the raw side and bottom edges individually with a method suited to the fabric. Before folding, mark a point three and a half inches below the original top edge on both sides of each panel. Place the panels right sides together and align them. Start the side seams at those marks, leaving the upper sections separate for finishing the casing openings. The seam-start mark is not the same measurement as the two inches consumed by the top folds.

Join the body but leave the top sections free

Sew down one side from its mark, across the bottom and up the other side to the second mark, using the half-inch allowance. Secure the seam ends. Keep the three-and-a-half-inch sections above them unsewn. Remove pins before the needle reaches them and follow your machine's procedure for turning the bottom corners.

Press the side allowances open as the fabric permits. Continue folding each free upper side edge inward by half an inch, in line with its seam allowance, and stitch that short folded edge down on its own panel. This finishes the sides of the future openings. Do not join the front and back together while securing them.

Form one casing on each panel

On the front, fold the top raw edge half an inch toward the wrong side. Then fold down another inch and a half, measuring from the new folded top edge. Repeat on the back. Measured against the original flat panel, the new top fold is two inches below the original edge and the casing's lower fold is three and a half inches below it. That lower fold should meet the side-seam starting marks. Check the folds on paper or a scrap before sewing; a different fold changes the relationship.

Stitch close to each lower fold, catching that fold securely while leaving the channel above it clear. Work on one panel at a time so you do not sew the bag closed. Turn the bag right side out and inspect both side openings. They should be accessible, with no loose allowance obstructing the cord's passage.

Thread and inspect the closure

With the bag fully open, measure the complete route across the front casing and back through the rear casing, including the transfer between panels. Add enough extra cord for accessible ends and the fastening you intend to use; check that allowance with the actual cord rather than choosing one universal length. For example, an illustrative route measurement of eighteen inches would still need additional length for both free ends and their fastening, not an eighteen-inch cut cord.

Use a suitable blunt threading tool to follow that route, bringing both ends out on the same side. Remove the tool afterward. If it sticks, back it out and inspect the obstruction instead of forcing it through stitches. Temporarily secure the ends, open the mouth fully and close it gently. Confirm usable ends remain in both positions before final trimming and finishing appropriate to the cord and adult use.

Open and close the bag gently before adding contents. Check the top seam ends for strain and confirm that the cord moves freely. This exercise does not establish a load capacity. Its useful result is a working casing whose openings you can explain, inspect and reproduce, rather than a bag that closes only when you tug harder.
