This was my first time doing square diamonds and it was a challenge. I put the time in and finally finished the project after long hours of work. I must say that it was all worth it. Square diamonds are no joke but the final product is awesome. (Lots of different colors.) When I got down to the last 4 diamonds I actually stopped and gave a shout!!! I recommend getting all of the diamonds sorted out before you begin working. I bought a kit that allows storage in numbered containers. Taking the time to prepare is really a key to success.
