I made a little flag for my shop sign for Flock & Gather using this tutorial on how to draw a flag. It was super simple to follow -- just make sure you sketch it out in pencil first. The only tricky part was figuring out how to split up the word shop so that the flag still looked like it was flowing in the wind.
Once I had finished drawing the sign I glued it to a shishkebab skewer by wrapping the paper around the skewer and holding it in place with mini-clothes pins while the glue dried. It's as easy as that!
