My son is one major fan of the Elf on the Shelf. He asked about an elf costume, we looked at the costume stores. They didn't have any to match the beloved character from the book and show. I thought about it and decided I can do this on my own, even with out a sewing machine.
Hot glue gun in hand, a red long sleeve shirt from Walmart. I took the white felt material and cut the triangle shapes out then I went to work bunching and gluing the white felt on like the elf collar. Next, I made the mittens by folding the material, long side of his hand next to the folded side. Tracing my sons hand and cutting it out I spaced over about a half of inch. I hot glue and fold it back in half. Turn inside out and done. Top with Santa hat and red pants I have a cute little elf. He loves it.
