You know I consider myself to be a fairly intelligent person. I have a graduate degree, I have common sense. I can even do calculus - but can I do simple math when working with half-square triangles??
Good grief...I cut it close with Safieh's row for the Houston Modern Quilt Guild Round Row Robin (only finishing it last night when the meeting is today) because I messed up the math on not only the original HST triangles, but on the borders I had to add to try and make the blocks big enough.
In the end though, it finally came together, though there was a bit of swearing on my part. Either way I am super happy with the final look and I hope Safieh is too!
