Every time I take leftovers home from a restaurant, I am tempted to make a take away box. The "pattern" is free and it comes with all the parts you need (wire handle).
I needed two pieces of fabric 14" X 15". The wire handle was 10 " long if you wanted to make your own. This would have been great in paste paper or if I had used a more rigid interfacing. It's a bit "weak" but it was good fun.
Iron on fusible interfacing to the wrong side of the fabric.
Fuse the two pieces together. This is where I would add a heavy interfacing inside the sandwich next time.
Cut out fabric
I used a fiber tip writing pen and traced the shape as well as folding the box and marking the fold lines.
I ironed the folds in the correct direction.
I punched the holes for the handles with an awl and the slit for the tab.
No great shakes but a fun project for a morning!!
