Our budget is
Finishing drywall is a whole other beast. We prayed for the Lord to inspire us. He did. We decided to use what we had: tin. Old tin. Why not? It was free. It had been a part of the 1867 roof and 1900 carriage house roof. It was just enough to do the living room-kitchen ceiling...and we LOVE it! [The sheetrock lift also lifts ten foot long sections of tin beautifully!]
I thought about patchwork quilts and based the design on that since we had a hodgepodge of tin. Bonus: It only took about 24 hours of labor including designing it.
As a way to encourage you, when things seem impossible...look up.
