Haha, thanks greenishfroggie
As I mentioned, I used a square punch to cut the squares... it would have been impossible otherwise (or at least I wouldn't have had THAT much patience!). I got this from a scrapbooking supplies store.
I then glued them onto black foam core using an ordinary glue stick. Using foam core was really practical as I could easily move and store my project without fearing it would come apart. I chose black foam core so that it wouldn't be as obvious if there were any cracks between some squares...
On my "pattern", I divided the whole picture in 4 x 4 squares so that I could keep track of the progress and applied the squares to the board in the same fashion. Punch out 16 squares, glue them on.... repeat 192 times, easy!
At first I thought of sealing the finished project with modpodge but decided not to do it 'cause I was paranoid it might seep through the paper too much and reveal the color/pattern of the other side of the paper or simply the black board underneath...
So I just framed the whole thing and it worked out perfectly!
That's pretty much it, very simple overall, just takes a lot of patience! It was great for relaxing, very mind numbing after a while!
On a final note... as I was working on this project, I saw a commercial for Behr paint I think it was... you could see all kind of objects, situations, etc and then a little square got punched out of it to show that you could match their paint colors to anything.... Whoa, I felt like that commercial was meant for me at that moment! HA!
Thank you all for your nice comments
