Step 1: Making the Shells
I them cut the ridges out. my yoga ball has lines on it which came out in the shell so it was easy to cut it evenly.
for stability I rolled up a piece of cardboard and glued it directly in the center of the inside. ( I didn't get a pic of that). that way when I glued the cardboard across it, it was pretty strong. I also glued cardboard to each of the ridges. using hot glue.
I spray painted both sides of the shell and added some detail with a brush and acrylic paints.
I cut 4 long pieces of fabric per she'll and glued them on the inside. This allows the child to tie them diagonal or just around their arms like a backpack.
I have seen this done a lot better with chicken wire instead of cardboard but I have never tried it.
Step 2: The Chest Piece and Girls Outfit
Once it's sewed and turned right side out. I used a single stitch down the middle and across to create the 6 pack.
Looking back I should have gotten a shiny fabric for this part.
The girls outfit was made using the leftover green fabric with the yellow fleece down the chesy. I sewed ribbons to the top for straps. The skirt was made using a ruffle trim...super easy, Elastic waisy.
Step 3: The Masks and Ties
the mask is felt and hand cut and I sewed ties on the sides.
Step 4: The Mascot Head
The only difference this time is I used the balloon sideways.
I also added some stuffing for the snout. The eyes are foam. The mask is made much like the other masks only larger.
Step 5: The Latex Mask
I did the new mask design for Donatello and also the original masks.
They are all the same mask just painted differently.
