That’s sort of my plan for blanketing as well.
There’s no where within a few hours of me to really buy blankets, so I have to order them, generally. My 100g and 200g and 150g (in a size up, for growing reasons) have not arrived yet. Shipping is sloowww.
Last night my yearling wore what I assume to be a “no name” brand sheet from Amazon because I could get it in his size and on time. We had rain, wind, snow, and cold, so I think this helped him. The sheet is a Challenger but looks just like a Tough-1 with a belly strap. It was $70.00 so I can’t complain. He’s about to outgrow it soon, anyway. It’s hard because he’s almost out of a 68 but a 72 sort of pulls funny due to being a bit large. At least it kept him dry.
