«-A layer. We hope to be outside.»

I'm sorry, that doesn't make any sense to me. A layer of what, for what? My
only guess is that you mean something to sit or lie on, like a picnic
blanket, to protect our clothes from getting stained by the grass.

Hi Mark-
By a layer, I meant a clothing layer. Like a jacket or sweater.
