I think it's wonderful and the scenery will probably never be the same thing day to day or season to season. Sure, in the worst of winter you can't sew. Or rainy weather. But, I'm sure you'll find a different creative outlet for those times. The benefit will be the peace, incredible light and fresh air. Great use of those sweat shirts! I love to see things repurposed and reused. And, you got twice the bang for your buck.
