So I was hoping this would be a good project for the boys (see this for an explanation)
but it turned out kinda femmy...But I like it!
I took a pile of old ties (44 for $9 on eBay)...this bag took 7... and a butchered pair of jeans:
And turned it into a fun messenger bag
One jeans leg was used for the base of the bag. I sewed the ties to that. The other leg was used for the side/bottom gusset and the strap. I had to use a super heavy-duty sewing machine needle (size 16) because the layers got a little out of control, but it all worked out.
In case you can't tell from the picture, the top of the jeans is sewn to the inside creating a plethora of pockets.
I guess I could make one just like it without the ties...or out of camo-pants. The guys might like that!
