You think these will work good. Not sure yet how bad sound reflection is yet in my room (yet to record), but I think this is the best I can get at a low price.
They have been used and removed, but looks to be in good condition to reuse.
And by the way, to hang them, is it alright if I velcroed them to the walls? Was thinking I might can quickly remove some if I wanted to have a echoing effect on vocals.
Or what would you use to hang them for quick release? Can you achieve echoing effects through sound effects after recording? As good as real/actual echo recording?
I think other than this, for now I would have to use this or moving blankets for my budget.
Should I use the 2" or 3" thick ones? I was thinking 2" thick.
And do you think this stuff is actually safe to breathe? Do you know if it's toxic if a dog ate some?

it's probably safe to breath although you also need to be concerned about it's fire retardant ability. the thicker the better. 4" is a minimum.
i used to be a huge proponent of foam but i have changed my mind. if you search back several years you will find some huge flame war threads between myself and a sound treatments huckster who used to lurk here, on the topic and while i still contend he wasn't right about a lot of his claims, i was WRONG about foam and it's uses. live and learn.
all foam is going to do is dampen early reflections. it will do almost nothing to help trap bass or smooth out the response of your room. imo you are just as well off with moving blankets. you can also achieve better results with rigid fiberglass.
acoustic treatments are not cheap. you need diffusion with mass and deep wells, early reflection absorption (foam), bass trapping (absorbers or membraine types) and most importantly proper dimensions and room symmetry. the larger your space the less need for treatments.
