1. Cut out the body pieces.
Dimensions: Body (cut 4) 18"wide x 15" tall
Be sure to cut 2 lining pieces and 2 exterior pieces.
Cut two pieces of interfacing now at the same dimension, these will be fused onto the wrong side of the exterior pieces.
This is the interfacing I use-it's thick but soft, gives that Vera Bradley sort of feel to bags. You can buy this on fabric.com or ebay. Make sure to buy fusible--as the extra step of sewing non-fusible is a pain....
*Thinner interfacing is also suitable, it just gives a thinner feel to the bag.
3. Iron the interfacing onto the wrong side of the exterior pieces, including the flap piece too. I do it all at once, so then my pieces are ready to sew.
*Be sure to iron the right side of the interfacing to the fabric---don't iron it onto your ironing board like I have..grrrrrrrrrrrrrrrr.
4. Sew around three sides of the flap piece, keeping the TOP open for turning.
(It will be sewn shut later in the process, don't freak out.)
6. Sew up the two exterior pieces, right sides together.
Sew a 1/2 " seam, again leaving the top open.
8. To make the boxed corners, cut a square out of the two bottom corners. I did 2.5 inch squares for a nice shape. (2.5" tall and 2.5 " wide.)
You can do any size, I'd just advise staying within 3 inch squares, as after that it distorts the shape a bit.
9. Bring the bottom and sides together and match the seam neatly. PIN this well. We will sew it next.
13. Pin flap piece to exterior piece, RIGHT* sides together. Sew or baste stitch it in place now.
Be sure it's centered.
(**The side you want to face to the outside when the bag is finished should be facing IN now.)
14. Cut A piece of fabric 5" wide by 30" long. This way you can always shorten it later if need be. If the bag is for a very tall person, you might want to make it longer.
Interface the strap now as well.
15. Fold long sides together and press. This makes a nice crease as a guideline.
16. Unfold the strap, then bring the two raw edges back to the center crease mark, they should meet-press firmly.
17. Fold it over again, so now there is only one open edge, press. Sew this edge closed and continue all the way around the strap so it is top stitched on both long sides.
18. Pin finished strap to the bag side. Raw edges aligned at the top. Be sure strap is not twisted, and pin it to the opposite side as well.
*** Test it now for length. Shorten if you need to. I'm 64 inches tall (almost) so mine ends up being around 28" long.
Sew over several times for strength.
19. Place the exterior bag inside of the lining, making sure to have your strap and flap sandwiched in there as well. Pin well, matching up side seams.
Look it over, be sure everything is okay.
Mark the area opposite the flap side with two red pins to remind yourself to stop sewing in that area. (For turning right side out.)
I'm trying to demonstrate that my flap is tucked in there too.
I once sewed a bag together leaving the strap out............don't ask. I amaze myself sometimes. LOL
Pin that sucker!
