Big man is very thin, and a bit short. This causes a problem with school trousers. Firstly I need to get him ones with adjustable waistbands secondly they need taking up. I have tried wonder web and sewing and they all manage to fall apart after a few wears. I am now going to give VELCRO® a go! If it works it means that I can also adjust the length as he grows. I used the iron on VELCRO® and just made sure that the fuzzy bit was on the bit that may touch his leg and the prickly bit on the turn up - I believe these are the technical terms!
I can't tell you if this is a long term solution yet as he hasn't worn them enough. Time will tell, but for now I am excited! I will update the post when I know more!
