If you want to learn more about knotting I would recommend this website and knotting group: www.khww.net, it contains several tutorials with detailed pictures.
Knots
Macrame
I guess everybody did a macrame plant hanger in school, macrame was very popular in the 60's and you can easily find books with patterns.
Chinese knots
Tatting
I'm doing 'shuttle tatting', not 'needle tatting', I believe the result is the same, only the method differs.
