You will need 3 different coordinating fabrics:
For the Main Bag Fabric you will need:
1- 11" x 28" piece,
1- 3" x 11 3/4" panel (this will be the bottom piece)
Hem
1- 5" x 28" piece
Trim
1- 1 1/2" x 28" piece
Straps (using one of the 3 fabrics from the main, hem, or trim)
2- 3" x 20"
The trick-or-treat fabric is my main (also bottom panel and straps)
The Black boo is the Hem
and the orange is the trim.
Now to sew:
-Fold the trim in half lengthwise right side out and press
-lay hem fabric right side up along the top
-lay main fabric wrong side up with other fabric tops-then roll up starting from bottom until the roll is shorter then the hem (pictured below with the tops on the left)
Fold the hem fabric over the rolled up main fabric and pin (pictured below)
-Sew along the raw edges, leaving a 1/4'' to 1/2'' space.
-Turn tube right side out
-Press (you can also sew the trim flat against the main fabric)
-With wrong side out fold in half and sew the raw edges with zig-zag (this is the side of the bag)
-Pin in bottom panel starting from short side and with the main bag seam in the middle of the bottom panel, and sew with zig-zag. (the panel is optional you can just sew the bottom of the bag like the side and it will be more like a pillowcase)
Your main bag should be completed at this point.
For the straps:
-fold in lengthwise, right side in, and sew.
-Turn right side out
-Press so seam is in the middle (optional)
-tuck 1/2'' to 3/4'' of each end back inside tube (creating a hem) and press
-sew one end of strap onto one side of the main bag 4" from one side and the opposite end 4" from the other side
-repeat for other strap and side
I used a 1" square with diagonal (pictured below)
YOU ARE DONE!
You can add pockets and have a great little all purpose bag.
It was easy enough that I might make some more!
