after scratching my head for several days wondering what we could do to finish the ceiling out 'on a dime' i ran across 2 bins of new burlap bags at a yard sale while we were in az and the light bulb went off in my head...perfect! and, only $2 for all of them!
so we transport them all to colorado and when the time came to start putting them up, i start unloading the bin and find about 6" of concrete instead of bags at the bottom. no wonder that one was so heavy! that required a little change of plans i.e. buying more bags but it all turned out just great.
after putting up almost 1200 sq. ft. of burlap bags, the big guy is happy to be putting up the last piece. this is the one he was looking for!
