I love filet crochet! The patterns are pretty easy to follow, for one thing! It's all chains and double crochets, and you work in rows, so you can really see how your pattern will look. The most difficult parts, IMO are (1) counting the chains for the foundation chain - it's easy to get lost when you're doing a hundred chain stitches, and (2) keeping your place in the pattern. I find that not letting anyone interrupt you on that initial chain, and marking your rows as you finish them will help you with those two problems.
