Lots of friends are ardent Masterchef addicts, picking favourites already! (Not so much me, I'm still mourning the end of SYTYCD - go Robbieee!) But it does make it easy to hand-craft birthday presents for foodie friends. I found instructions for this chef's hat here, but frankly, they're really hard to follow. I gleaned that the pattern is a circle and a rectangle, and from there I just made it up in much the same way as I'd sew a pleated skirt!
Not for the faint-hearted, but if you do give it a go, personalise your hat with different fabrics or an embroidered on felt logo...
