OK, not quite DIY, more (grand) child labour - supervised by Madam of course.
Re-gravelling our drive, we had to wait until the ground dried out after last year's flooding otherwise the rocks would just vanish into the squidgy mess.
I'm not sure what the "rocks" are actually called, it consists of stones up to around 1/2" along with much finer stuff, with rain and driving it compacts into a very solid surface (digging a channel for some cables was definitely hard work).
After some rain and driving on it we'll get another load of the "rocks" and fill in the low spots.
The rustic "grass up the middle" drive fits well with our "more jungle than bowling-green" style of garden.
