One, shop-bought trousers that K already has, for size.
Two, the trousers I made for him from one of my old T-shirts last year, for construction method.
And three, the principle that they're just a pair of trousers for playing in, and don't have to be perfect. For my sanity.When I first saw this fabric it just shouted out 'applique!' to me, so I got a plain T-shirt and had a go. I encouraged a bit of fraying around the edges for a bit of rough, boyish charm, and so that when disparaging busybodies point out that I haven't done a very good job, I can claim that it was meant to be like that.
It's K's birthday next week so I'm going to wait and give this to him then. I did want to try the trousers on him before sewing up the elastic though, so I left them on the back of a chair in the kitchen. When K came down in the morning he spotted them there and made a beeline for them, even ignoring the open lap-top! That made my day :-D
