We linked their visit with a woodwork yarn craft. Using a hammer to bank nails in to blocks of wood and then winding yarn around the nails to make pictures and patterns.
My youngest son and his friend spent most of the morning in ditches metal detecting and dug up some cool items! The favourites were a very old Jays fluid bottle and an even older Liptons Tea sign.
We are neighbours with an Antique Center so the boys cleaned up the sign and took it to be valued. It sold a few weeks later at auction for £18! They are very happy with their first treasure hunting and money making experience!
