The young girls got a pre-nailed heart board that used nails with bigger heads so that the string or yarn would catch on it easier! My daughter is 5 and she did this one all on her own!
We had so much fun working on these and it was cool to see all the colors everyone chose to use! The beauty of string art is that there is not wrong way to do it! You can find a pattern or do it random all over!
When I taught the class I started out describing to everyone the necessity of nailing in the nails far enough (about half way) otherwise the strings would pull on the nails turning your heart into a blob! Even for the initial, if the nails aren't in far enough they will pull and loose shape. Be careful to not hammer too far as you will go through the wood then!
Next thing to keep in mind is distance between the nails. You don't want them too close or too far apart. Usually about 1/4-1/2 in apart is good depending on how tight a curve you want to make.
Once you've got your project all hammered you'll want to start stringing! Start by tying the string around the nail of your choice and then double knotting it! I like to place a dab of hot glue on the end of it to help it stay.
Next you can start to string away! A project like the cross where you want that radiating effect you'll have to a little math. Divide the number of outside nails (around the cross) by the number of inside nails (around the heart) and that will tell you how many nails you have to go around the outside per every one on the inside. So each of the inside nails will have multiple strings around it while each of the outside nails will only have one string around it. The math for my cross pictured was something like 3.78 so for some of the nails I wrapped around 3 times and some I did 4 times (you can't half wrap a nail😊)
Once you have completed stringing your project you again knot and double knot the string around the nail of your choice and then put a small dab of hot glue on it to seal it!
Hope that helps if you want to do your own string art or want to teach someone else!
