I'm building on a really tight budget, but I've been going with the best that I can afford ATM. That said: 1/2" mesh hardware cloth should be small enough to keep pretty much everything out, right? HD had 1/4", but it came in shorter, smaller rolls and was WAY more expensive overall. Also- when I install the hardware cloth, will staples and 1x2's screwed into the studs be strong enough to keep most things out? I'm not planning on putting up the inside-plywood until later this fall. Thanks so much for your help! Tomorrow is wall-raisin' day, followed shortly by roofing day and "lets see if Jenn can keep from maiming or killing herself with the saw" day (also known as sheathing day). Pics to come shortly!
