Hi Cakers!
Well, I tried the square pan collaring technique this past weekend. I shot a few pictures for yall in hopes this will help. Let me first say, a square pan is much different for some reason than a round. Oh yea, please read my disclaimer at the besieging of this thread! =)
First, start out with your supplies. Notice how my parchment strips are curled over? Keep this in mind for later. I believe this is why I was having problems. Cut 4 strips for each side. Also, cut a piece for the bottom. This pan is 2. Make your strip 2 ½ tall. This is VERY important. You do NOT want your strip to be too tall

Spray the bottom and sides of the square pan with Baking spray. Lay your bottom parchment paper first. Attach the side strips. Spray the back of your strips first with baking spray. This will help them adhere. If you look closely, you will see that my strips would not want to adhere completely to the sides. Especially the corners. Urghhhhhh! I think this is because the parchment paper was curled. Parchment comes on rolls. I dont think helps us when lining square pans. However, there is hope come later

Pour your batter in the pan. Take some left over batter and place it on the back of the parchment strips. This really adheres the paper to the sides well. Take a look at how better the strips look

Please excuse the poor lighting on this next pic. Bake as normal and take out to cool. Notice how the longer side strip pulled up as the cake raised. This cause my parchment strips to fall over a little. Dont worry about this! My cake still did not bake completely of the lip of the pan!!!! Whoop Whoop!! Wow, look at that huge dome. Oh no, am I going to get 2??????Stay tuned

Level your cake as normal. Take a look at this folks..

2 of cake!! Thank God. I was really worried about this one. I think the next time I do this; I will flatten my strips out overnight so that they are not curled. I really think this is why I had a problem with them sticking to the pans.
