My lab has three very big, very gray, very blank walls. I liven up two of the walls with sheets of fabric, but I have generally saved that third wall for large, border free bulletin boards. In the past, I've changed it up each quarter.
This year I decided it will stay the same for the entire year. I made a Word Wall.
It's not a fantastic photograph but you get the idea.
The most time consuming part was cutting out the letters. I worked our school's registration from 11am to 7pm and I cut out letters when I wasn't busy. I got it all done!
I made the letters in Word and changed it to outline. I printed it on colored cardstock and sent it through the laminator. To get the layout, I used masking tape to tape them to the wall, arrange them how I wanted, and then stapled. I had to be careful pulling the tape off but it saved a ton of time and frustration.
One wall done. Two more to go.
