Today I built my camera obscura tent. This started to become a very expensive project so I ended up going to Toys 'R' Us and getting the cheapest dora the explorer toddler tent. It turned out it didn't have a bottom so spent quite a long time today sewing and sticking it all together.
Nine hours later my tent was light proof. Its a pretty tight squeeze, but both Ellie and I managed to fit inside. I have made a complete mess of the living room now though! Need to take my tent outside in the next few days to see if it will work.
