Yours is beautiful! Thats one that I've been researching for some time now. Wanting to make one but I know theres alot to know. I've looked at several in the LQS and they too seem to have mountains, some bigger than others. From what I've read you have to stop sewing a quarter inch from the middle. Fons and porter just did a series on that. But I didnt get a chance to watch it all. Good luck. It looks beautiful!
