Making Triangle Kimbab--at school!

One morning, my sweet co-worker Choi Ee Eem made homemade Triangle Kimbab.  She is basically like a professional!  She used sticky rice, something resembling SPAM, and seaweed wraps.  I never knew how they made the kimbab in a triangle shape.  She used a triangle mold.  Everyone in my teacher's office got really excited to see kimbab being handmade!
