A large Santa sack is usually the same size as a standard pillowcase. To make one, you will need the following materials: cotton fabric, thread, and sewing supplies. You can purchase fabric in Christmas patterns or simply in plain red or green. If you want to make it even more festive, you can recycle an old pillowcase. Fabric painting or stenciling are excellent ways to decorate cotton fabric. Once your personalised Xmas sacks is complete, you can add a drawstring. Make sure to choose one that's about 1/2 inches wide. You can find an easy-to-make sack with a red body and a white cuff. These personalised Christmas bags can be finished in an hour and placed under your Christmas tree. When the holiday season is over, simply fold them up and store them under the tree. If you're looking for a bigger personalised Christmas bags , you can consider an extra-large Santa sack. You can even find one that's decorated with a snowman or penguin design.
