I made my first banner for Samantha's birthday almost four years ago now (wow!). I was inspired by the one in Alicia Paulson's book Stitched in Time. I used freezer paper to stencil the letters to personalize it and have enjoyed using it every year. But hers is pink and girly, and I would have to find a new fabric to add B&E's names, so I just decided to make them their own.
Allow them to dry - I waited about 24 hours. Then carefully peel away the freezer paper. (Don't forget the insides of those letters that have them!) Keep them in order!
If you want to trim your letters into a shape, now is the time. For my first banner I cut them into a curved edge, but I wanted a pointy banner this time.
I folded the squares in half and measured up from the bottom point.
