If you want to make the cutest villain in the Mario Bros universe, here is the pattern to make his beautiful spiked shell.
This downloadable pattern will allow you to make a shell the size of a good backpack, mounted on shoulder straps.
If you're planning on making a Bowser or Bowsette costume, that works too. I simply suggest that you make the spikes a little longer.
This set contains 1 element:
The spiked turtle shell
Available size:
The pattern is offered in one size. The finished shell is approximately 35cm x 43cm. It is possible to make the shell larger or smaller, by changing the print percentage.
You just have to make the straps of the size necessary for the shell to hold well.
