Zoe of Creative in Chicago used crochet and regular sewing thread in blues, greens and purples for her String Art.
The words sea and sand are left bare with this design. You could do it the other way around too and string the letters instead.

Now to the string art how to. All you need is a piece of wood. Paint it to match your decor or leave as is for a rustic look. Then decide what you want to write or draw on it. Find letters or a design to print out on the internet or sketch something yourself, cut it out, then position your string art design on the wood and tape it on. Now you're ready to hammer in the nails! You can get an idea for the spacing of the nails from Zoe's string art. When you're done, rip off the paper and start weaving the strings. Tie the string in a knot on the first nail. There are no rules here! You could do the first pass with one color, then go back over everything with a second color, and so forth, until your piece looks complete.
And here's another example and String Art How To! Your string art design can be as elaborate or simple as you want it to be. A sailboat would be quite easy to do, for example. And a grouping of mini string art pieces would look great too! Will you be stringing along soon?
