One of the advantages of crochet is that it is easy enough to unravel and try all over again when things go wrong which is not possible in the art of tatting. The thing about starting with circular doilies is that they are a tad easier than other shapes. But do not restrict yourself to this one shape once you have mastered the basic steps of crochet. As you can see from the images given here, that there are many style, design and shape possibilities when it comes to the crochet doily.
What is more with the use of multicolored threads, it is easy enough to create intricate patterns even your mastery over the crochet patterns and stitches is not much. Another thing that will hearten you and make you more inclined towards crochet doilies is that your rate of progress will be quite significant unless when you work with knitting. This means that any crochet project you pick up will show a lot progress and get completed even before you start losing interest.
