Woodworking
Of all the DIY skills that you will learn woodwork is one of the most used and can be done with few inexpensive tools. If you live in the UK then you will probably only ever use Pine as this is the timber that you buy from the timber merchants, hard woods are available but are very expensive. .
You don't need to shell out money for expensive wood working plans unless you are going to be making a bespoke chest of drawers with routered detail as most wood work requires just a little patience and common sense.
