I've seen skirting that was cut from sheet of trellis material. Can be

home.


Good idea with the hay bales as a person would surely need them
in a colder climate to keep pipes from freezing.

My friend did cut a small opening in his skirting and put a
'cat house' under his mobile home for his cat. He also wired
it for a light bulb to keep her warm in the winter. But he
did gripe once as he couldn't understand why she wouldn't stay
in her nice house more than a few minutes even in the bitterest
weather. I asked what wattage the bulb was and he said it was
a 100 watt!! I told him he was cooking her and in that nice
little box he'd made for her house all he needed was something
like a 15 watt to no larger than a 25 watt bulb. He changed
it to a much lower wattage bulb and she was toasty without
being cooked.
