Who said you have to spend a lot of money to rent costumes for Halloween? As long as you have thick cardboard, you can transform it into a unique character mask with skillful hands! Steve Wintercroft from the UK relies on his superb design skills to transform thick cardboard into 3D Geometric skull mask. Those interested in making one can purchase instructions on Etsy. The estimated completion time is 2-3 hours. Since you make it yourself, you can save time on shipping. You can also process and paint it according to your own preferences afterwards. I have to say that he is absolutely handsome!
