Step 1: First design the size of the fabric small backpack on the paper, and cut the fabric according to the design. Cut the prepared floral flannel into two pieces of cloth with the same size, and fix all four edges of the two pieces of cloth.

step 2: cut the prepared sandwich cotton cloth to the same size as the floral cloth, align the floral cloth with the sandwich cotton cloth, fix the sewing edge with a pin, and do the same for the other sandwich cotton cloth and the rag. Align the two pieces of processed composite fabrics face to face and sew the left, right and bottom edges. Remember not to sew the opening.

step 3: after the sewn fabric small backpack prototype is turned inside out, use a ruler to help fold a triangle at the bottom of the backpack, fix the position with a pin first, and then sew it to the center line of the bottom, and do the same for the other corner of the bottom. In this way, the fabric small backpack has a width, which is more convenient for storage.

step 4: cut the prepared lining cloth to a size 2cm smaller than the edge length of the floral cloth, fix the cloth after sewing, align the two pieces of cloth and sew the left, right and bottom edges, and the basic shape of the lining is completed.

Step 5: After the lining fabric prototype is completed, the bottom edge should be treated like the front fabric of fabric small backpack. The difference is that the folded triangle does not need to be sewn at the center line, but the redundant part is cut out after sewing it with a knife. Remember to keep a certain distance from the stitching when cutting.

step 6: sew the prepared strap buckle and lining together after fixing them with pins, and make the front cover fabric of the backpack with brown flannel. The length of the long side and the backpack is the same, and the short side can be determined according to your own needs. Fix the front cover with pins and sew the fabric small backpack fabric. Finally, the front cover and the front of the backpack can be fitted with leather buttons.

well, our hand-made fabric bag is finished.
