The sewing book market seems to be exploding at the seams at the moment. Unfortunately, there are barely any patterns for boys in any of them! It's a shame! There are, however, a few out there that are worth mentioning.
Sewing Clothes Kids Love is very popular right now. I've written about it several times, as have many other bloggers. I have yet to see anyone blog about the boy patterns. There are pants, shirts and a jacket that work for boys. The photos in the book look very "cool" and I think boys up to size 12 would enjoy them. Definitely worth checking out. Especially if you also have a girl to sew for.
Sewing for Boys: 24 Projects to Create a Handmade Wardrobe is coming out is September. This is written by the designers of Patterns by Figgy and, according to Amazon, will have patterns up to size 7. I know nothing about this book but it looks promising!
Ottobre Design magazine is a great source for boy patterns. I have a few of these magazines and the clothes look fresh and well designed. Lots of knit shirts, jeans and pants. Search through the Ottobre site and buy just the back issue you like, or subscribe and receive 4 issues a year. There are 40 patterns for boys and girls in each issue but usually only a few go up to size 170 cm.
