I'll post a picture once I'm underway, but I just purchased a 4 piece 3/4 weight 7'6 rod and components to build my 7 year old's first fly rod for his 8th birthday, which is in early July. Got a matte black blank with black components and black thread from Hook and Hackle. I'll figure out who his favorite Lego character is and put a sticker under a coat of epoxy. Hopefully be a rod that will last him a lifetime.
That rod is just right for an 8-year old, size-wise, although I'd love to cast it too!
