Years ago DS asked for a yellow suit. Was v young & couldn't describe it but wanted it for months.
I bought him some thermal longjohns & a vest & dyed them bright yellow with dylon along with a pillow case that I attached as a cape. I got some red felt and cut it into his initial & attached it to the front with wonderweb.
He was delighted with it on Christmas morning & then never wore it 
DD has asked for a diamond maker this year - I've told her if she manages to get one I'd quite like a few diamonds myself.
