And mostly it really was putting together. The red trousers were bought and I was planning to buy the red long sleeve t too. But not one anywhere. By this stage I realised I was going to have to dye a long sleeve white t and the only shop to sell long sleeve white tees (this was the summer) was closed due to flooding. So I dyed a slightly too short t we already had which is slightly annoying as it started out slightly too small. Also slightly annoying that the washing machine rubber trim is still, may many washes later, a delightful shade of deep pink.
The hood is the helmet pattern from Emma Hardy's cute and easy costumes for kids, cut from a cheap and cheerful adult size red t, and the mask is from the same book. More felt was then used for the flashes - I sandwiched heavy duty interfacing in between the layers of the flashes on the head. The Flash does also have flashes on his legs but I decided to keep these trousers flashless as P has been wearing them as everyday trousers.
I do believe The Flash would also clean his boots before any mission but it gets muddy round here.
Happily one of the Daddys at the party recognised this as a Flash costume so I was happy. And so was P. Very much so. What will he request next?
