Has any one found and/or attended a course for enthusiastic DIYer that would like to attempt some garden hard landscaping? Our garden needs everything doing, and we'd be up to the challenge of attempting it but don't know where to start. We've done lots of DIY projects in the house, but have never attempted any projects in the garden. Ideally we'd like to lay some clay pavers and build some retaining walls, but figure a bit of expert tuition is probably advisable (especially for the retaining walls!) Any advice or recommendations much appreciated.
