I used the Linux program KXStitch to make this pattern. Its a really easy program to use.
It took me a little over a year, (I made some other things in between) and it took almost 10 whole skeins of embroidery floss.
Each square has the symbol and the name. I wanted to add the atomic number, but I ran out of space. All the elements are there up to Copernicium. I didn't do those UU elements. I had to draw the line somewhere. :)
I will post another picture when I get it framed. I was just so excited to finish I had to post it now. :)
I hope you like it.
