What does your pattern say the finished size of your block is? Also, was that the 4 units together that Jan posted? Answer these 2 questions and there are several here that could give you the size of the squares and 1/2 triangle squares. There is another way to put this together and it is the 4 blocks together. Edges could be flying geese with rectangles, center is solid squares and 1/2 triangle squares. Less seams this way. Good luck on your project! Also, don't give up... you will be so proud of yourself when you get it all figured out. The other bonus is that you will be able to pick out the squares in the next quilt you fall in love with and be able to do your own pattern.
