I am making a sling but I thought it would also be nice to have a google slide to explain a little bit more about why I chose the sling. 

I made them on gravit and sent them to CCI to laser cut them.

I made two knives out of cardboard then I covered them in duct tape to make them look more real.

I made the double knife scabbard made the knives fit in it.

I made a belt for the scabbard and made holes to make the belt adjustable. I am now officially done. 

I added a new slide on the double knives used by the Rangers.

I started practicing with the sling to test if it worked and it did!!! I am not very good at it so a lot of the time my ammo just falls but sometimes I can send the projectile flying.

I am going to make a sling because the sling plays a big part in Rangers Apprentice book 7. (that's the book I am doing.) Here is a link to the tutorial I found: https://www.youtube.com/watch?v=srao1ag5S5Y
