Quilting is not all that exciting... which is a good thing. Sometimes you just need to relax.
Gather photos from your adventure... and your iron on transfer paper.
When reading "How to sew a quilt!", you will learn that each quilt square is 3.5"x3.5". This is great news because you can fit four 3.5"x5" photos per sheet of iron on transfer paper. Please note the difference in dimensions, your iron on photos will be larger than your square. Keep this in mind, you will be trimming the edges of your photo to fit your squares.
Theoretically, you could iron a photo onto every single square of your quilt. Choose a reasonable number of photos. The iron-on transfers do wash well, but they are somewhat stiff and awkward.
I chose to add a photo to the center of 10 of the blocks on my quilt.
