Most frusterating

My good friend just got back from Germany and brought me some beautiful yarn. I decided to knit my first pair of booties for our baby. The first one turned out adorable, however I ran out of yarn about 4 rows before finishing the second one!!! Now I have to either attempt to match the yarn from Germany, or make one bootie with a different colored toe and seam. I will get a picture of them up here once I figure out what i'm going to do. Nothing is more frustrating that running out of yarn mid- project!
