People use icing piping bags to decorate cakes and other desserts. Making fancy iced piping swirls and flowers on a cake or dessert, and showing the finished product to relatives and friends, is fun. Some people use the icing bag like an artist uses a paintbrush for decorating a canvas. You can make several piping bags, and fill them with different colours in advance. Then pull out the pre-made bags for decorating cakes and desserts quickly and easily without mixing new icing. Making paper icing bags is simple, inexpensive and fast.
Cut a square piece of parchment measuring 14 inches by 14 inches. Lay it in front of you with one of the sides facing you. Lift the upper left corner, and fold it down to the lower right corner. Press the centre, so it makes a triangle shape. Cut along the creased line. This makes two parchment bag pieces.
Place one of the triangles on the table, so that the flat side with the two 45 degree angles faces away from you. Label the corner facing you "A," the top left corner "B" and the top right corner "C."
Roll corner "C" to point "A" where they meet. It starts looking like an ice cream cone shape with a triangle pointing up where corner C is located.
Pinch corner A and C with your index finger and thumb, so they stay in place. With the other hand, roll corner B over corner A. Bring corner B all the way around until it gets to corner C. Pinch it in place with A and C.
Make sure the cone is tight, and that the point at the bottom of the ice cream cone shape is tight. Tape down the open edge of parchment paper on the paper icing bag.
Cut about three-quarters of an inch off the pointed tip on the cone. Slide the piping icing tip through the wide side of the bag, and push it into place at the bottom of the bag with the tip's pointed edge poking out. Press the piping icing tip firmly into place.
Fill the cone of your newly created paper icing bag with icing. Fill it about halfway full. Fold the left side of the cone over, so it almost touches the top of the icing in the bag. Fold the right side over and then fold the top of the bag down until it reaches the top of the icing. Continue folding the sides and top down until the icings starts to squeeze through the tip. The piping icing bag is ready to decorate your cake or other dessert.
