Lots of interesting ideas there! Rope. knots, anchors, banners, word art, not to mention the classic red/navy/white colour scheme! Here is what I came up with:
I went with the nautical theme, but in a different way. We have a park nearby to us which has a big ship to play on, and I just so happened to have some photos of my Erin playing on said boat! Perfect starting point! I also loved the colours, and started with the sketch and went from there. Be sure to check out all the other great samples here to get even more ideas.
