1) As hobbies, arts and crafts are oversubscribed by women. If you take a pottery class, for example, you will meet a lot of women in a non-competitive environment, and have at least one major thing to talk to them about.

2) Being able to create beautiful things is a personally desirable skill.

3) If you're a technical/maths type, having something "artsy" under your belt makes you seem like a more well-rounded person.

4) You have the ability to produce personalised tokens of affection.

Anecdotally, since I took up life drawing, I have been staggered by the number of women who've professed an interest in modelling for me. In some cases this is flirting and in others it's genuine platonic interest in being drawn; distinguishing the two is a minor hazard, but both are pretty welcome.
