Beside the seaside, beside the sea

My son has being doing a seaside theme at Nursery this term, and as I had made a few seaside theme cards, I thought I would make an extra special one to say thank you to the lovely teachers that do a grand job. Both he and I love the nursery and couldn't have chosen a better one. So thank you teachers! I would love to make something to give to the teachers so any suggestions would be welcome, ideally something they could all share...?
