Thanks for clarifying about the blacks. I think I will still go with SF for the first go, although it is a toss-up. I've just got a hunch that the mounting will be a bit easier for me with the less stretchy fabric. If I don't succeede, I'll go with the PK next time.
Yup. Go for it! I think that you will be successful either way from a mounting perspective.
Oh, get another person to help you hold it in place if at all possible, or use masking tape to temporarily hold the fabric where you want it before stapling. Both of these methods should make it work the first time with either fabric type. I did large (24" x 48" x 3.5" and 24" x 48" x 5.5") panels in PK by myself without too much trouble. It was harder to man-handle the frame and to keep the fabric from sliding around than anything else (thus the reason for someone to help or using tape). Just take your time and you will do well.
So I finally finished all of my posters and have some pics to share. But first I need to say a huge thank you to Nickbuol again for his help with photoshop and setting up the posters to print. Also Spoonflower was super fast shipping my order. I placed the order on a Friday morning and had them by Monday evening with regular shipping!
My pics turned out pretty terrible and do not speak to the quality of these prints! I only have my iphone to take pics with and the lighting in the home theater washed them out, but they look incredible in person.
are these fabric posters? they look incredible...
I confess to not having read up on this thread in a while...
So what does everyone recommend I use for the insulation? OC 703 or other?
OC703 is the "default standard" for this kind of application as it has been trusted for many, many years, however, there are other products that people are having very good success with that can many times be found locally and for less money than the OC703. I went with OC703 just because it was a tried and true solution to my needs. Others have used Roxul Safe n Sound from Lowes, and a few others that escape my mind right now.
You can also order from some sources online. Look at the link below for a short list of some materials. If you base the "model" insulation to be OC703, then look for something with similar numbers, thickness, and rigidity (needs to be stiff). Keep in mind that every room is different and since most people are just adding general absorption, the numbers can be off by a little bit and still yield similar results.
