These trousers are now finished, but if they fit Theo, and if DD likes the style and wants more, the pattern will have to have some changes.
The fabric is a stretch denimy sort of thing with a few flaws in the fabric. It was a free remnant, and was perfect for a wearable (?) toile.
Because of the difficulty following the instructions, the inside looks unfinished and untidy, and the elastic really doesn't need to go around the front of the trousers as well as the back. The trousers are also waiting for the final topstitching around the curved front.
If I did them again, I would do the elasticated back separately. Then the front could have faux pockets and a proper waistband. I would also slim down the legs which look a little wide.
Thanks both Lizzie and SiT for your help, always good to have another pair of eyes on the problem!
Now, on to the next project!
