Well if a tractor cushion is out, maybe gardening tools are back on the list. They always go down well with me. Maybe you just need to pick carefully
I thought I should share a picture of my belated birthday pressie this year (lockdown birthday so everything gardening was sold out then). Quite a bit of kit and I am pleased with it. It feels properly made and that it will last just about forever. It makes very short work of digging out weeds or turning over soil as well.
It came from a firm called Niwaki. If you are looking for a gift for a gardener, they have some good ideas.
If Mrs Wells doesn’t like it, you may be in for more trouble though. It could do a considerably bigger mischief to you than a spade
