Gathered all my supplies.
Drew out my triangle at the bottom. And cut it out.
Drew out a 1 cm border around edge, I'll fold it over the line and sew the edge together to make a hem.
I took the triangles that I cut off the bottom and cut them into rectangular strips. I folded these into loops and sewed them to the top to make the loops for the dowel.
That leaves you with a beautiful but blank banner. For this one I wrote out in sharpie what I wanted to say then embroidered it. I had two patches that I ironed on as well.
This one I did in the same way with some different patches. The trim I bought from Michaels and sewed to the bottom.
For this one I made felt flowers and hot glued them to my banner.
