Would anyone tell me what a crochet pattern looks like?

The best way to find out is to visit a sewing/knitting shop and ask to see the crochet patterns. They look like lacy or network variations of knitting patterns. Very pretty, and suitable for the summer, party wear or bedjackets and shawls. They are quicker to work than knitting patterns and you can only ever drop one stitch instead of a whole row. You could also type "Crochet" into a search engine and look at the crochet sites to see what the patterns look like.
