Sona Progress: Etwahl and Expanding Foam (Etwahl - Part 1)
Saturday, November 30, 2013I had posted a while ago that Sona from League of Legends will be my next cosplay project. Here are some updates on the progress of Sona's etwahl, the awkwardly shaped instrument that floats in front of her :3
I decided to use expanding foam to make this prop. I have never used it before but it seemed easy to work with. Mine was from Walmart, Hilti and Great Stuff, but you can also buy it pretty inexpensively on Amazon. Both for $3.77 a bottle. I will write about my comparison of both brands in my next Sona Etwahl post. Make sure it fills gaps larger than 1 inch so that the foam will expand more. Also use a spray bottle of water to speed up the expanding process.
I started off by making a frame out of cardboard. It is about 3 feet 4 inches long. I used tape to attach it together. Just enough so that it'll stay in place.
This is what it looked liked after piecing it together
It didn't look quite right, so after shaving off a few more inches all around, i ended up with this shape
Now onto the foam! I am using the Hilti brand. After I took off the cap, I screwed in the nozzle with long plastic straw tube. I was immediately able to press the trigger and the foam started oozing out in a stream. With one bottle I was able to cover up half of the front and the top side front row.
I was a little impatient, so before I even bought more foam, I started test carving the foam. To my surprise, it was easier than I thought. I only shaved off all the uneven bubble ridges, so it will take a lot more time to carve it smoother. But here are the results so far:
