I found this picture of my mother and younger brother at the baltic sea, in front of them a somewhat shapeless heap of sand that I think was supposed to be a pretty sand castle. Oh too sad! But why not add a little fun and pops of color to the photo and 'build' one for them ... with thread!?

Don't fear, you don't need any embroidery skills for this.
There are very cool versions of embroidery on photographs on the internet, too. Have a look at these awesome projects/artworks:
