My 3 year old Grandson Weston would flip out if I made him this “DINO TAIL” because he is obsessed with dinosaurs.   Jessica of “running with scissors” has a complete tutorial for you to follow.  She said you can call them dinosaur or dragon tails.  She made these during those long winter months when we have to play inside, so keep these in mind. Jessica designed these tails with two straps that wrap around their waist with Velcro in front making it easy for them to get them on and off themselves. Thanks Jessica for the clever idea.
