For an adult/bigger-kid size bag the fabric requirement are 2 coordinating half yards.
For a smaller child’s bag you will only need two pieces at ⅜ of a yard.
I will demonstrate with the larger bag
and give the measurements for the child’s bag at the end.
First: from both half-yard pieces, cut a 4″ strip off one end.
This will be for your strap.
Cut the remaining piece down to 14″ x 30″.
(You can save the remnant for a pocket, if you want.)
Bring the seams to the center and match them up.
Press seams open.
You will now have your lining-piece folded in half on one side and
your outside piece folded in half on the other.
for turning right side out. Sew ⅜″ seams on both sides.
roll the lining fabric above the bag about ¼″.
Pin to hold fabrics in place and press.
AND at the top of the lining fabric.
and sew down both long sides using a ½″ seam allowance.
(This strap is meant to be worn diagonally across the chest.)
For an adult, it’s about the right length as it is.
For an older child, you might want to cut-off a few inches.
If you leave one end with selvage edges on the end you don’t
need to do anything to the strap before you start sewing.
If you cut-off one end, you may want to tuck raw edges under and press.
Now, pinch the end of the strap in half to find the center.
creating a rectangle to secure the strap in place.
Repeat all the same steps.
(You will probably want to shorten the strap.)
We used a heavier, canvas fabric on the cowboy bag.
The other bag is made from the Wonderland by MoMo collection for Moda.
(and please feel free to ask any questions so I can clarify these instructions where needed!)
**A couple of people have asked where this fabric is from:
