Hoisen sauce together in a small bowl. The peanut sauce is a little spicy for the kids, so I just mixed Hoisen and plum for them. Another really good flavor is sweet chili sauce. You can get all of this in the Oriental section of your store. I couldn't find the spring roll skins at Safeway but they were there at Fred Meyers. Also, the julienne tool was found at Fred Meyers. If you can't find one, you can use a food processor or the good old fashioned way and cut it by hand. The key is to get the veggies thin!
