I used a duct tape dummy to help out with sizing. I put a leotard with an underarmor shirt over it. Then I hot glued foam shapes over the shoulders, chest and back to make a beefy upper chest. Then to create a digitigrade leg ( dog leg appearance...not a backwards knee like everyone thinks, they just have shorter lower legs, longer feet and stand on thier toes). I add foam to the front of my top leg and the back of my calf to make a shape like im bending my knees...even when the leg is straight.
Try the suit on every so often with the head on to make sure the proportions are okay. Trim accordingly....get the foam right because you dont want to have to go back a step to fix things. Remember you will be adding fur on top of the foam. This will add more bulk, so slight shapes are best.
The shirt and leotard connect with velcro. I sewed and then glued the corresponding sides to the inside og the shirt and outside waistline of the leotard. Also add some velcro to the elbows of the shirt..this is where the lower arms will connect.
Cut shapes of fur with your exacto ( cut the back as to not mess up the fur) and hot glue it all on. Place the pieces close together, fill gaps with smaller pieces. After you are satisfied, sew all of the glued on pieces together so when you flex and bend, the fur does not show seams and gaps.
