Desmond Backpack Sew Along Step 6 – Main Body Construction

I love getting to this point in a project. After all of the somewhat intricate work involved with constructing pockets and straps, we finally get to see the backpack take shape today as we sew the seams for the main body. This is the 6th step in my Desmond Backpack sew along.

Main body construction, Exterior

main body corner seam

Fold the bottom corners of exterior piece A right sides together so that edges align. Pin in place. Sew the corners using 1/2″ seam allowance, stopping 1/2″ from the edge. Stopping 1/2″ from the edge will make assembling the pieces that meet in the corner easier. These stitch lines create the sides of the backpack.

With right sides together, pin the bottom of exterior piece B to the bottom of exterior piece A. Stitch piece B to bottom of piece A, starting and stopping 1/2″ from each end.

Here is what the back/bottom seam looks like from the inside.

With right sides together, and all straps to the inside and out of the way, pin the long sides of piece A to the long sides of piece B. Stitch the sides together 1/2″ from the edge, sewing all the way to the edge of the fabric at the top and bottom.

When sewing up the sides, back tack over the lower straps for reinforcement.

Sew a second row of stitches for reinforcement on top of all of the seams sewn during this part of the construction. Like the shoulder straps in previous steps, these seams will take on the weight of the contents of the pack, so we need to make sure they are strong.

This completes the exterior portion of the pack, and you can set it aside for now. Up next on Monday, we will start work on the lining. I hope everyone has a great weekend!
