It's always good to be able to pass your hand and craft skills on, either to an apprentice or family member. To know that the lessons you've learnt are finding a new audience.
Maybe a tad morbid as well, but it was asked in this forum once, what will you do with your tools when you're gone, to know you have someone to pass them to, who will use them and love them as you have is a good thing.
Tony, Di, good effort. Tell your Grandson, well done.
