Answer 1

You can do it with a comb. You just drag the comb along, making wavy lines as you go. You can do some spots twice to make grain lines.

You should be able to buy something in the decorating department of a DIY store - in the bit where you can buy effects brushes (it usually comes as a rubber roller). Otherwise, practise making patterns with a cocktail stick.
