Welcome Chrissy. You found a very pretty pattern, it shouldn't be too hard for you if you take your time. The two HST's are sewn to the small square as shown on the right side of your first picture. Make 4 sets like this. After you have put your large square together, nine pieces, then you sew each HST set to each side of the square. Remember to press each step. This will finish up as a square. Post pictures when you get er done. Hope this makes sense to you, am not good with words. :D
