I love this site : http://www.crochetpatterncentral.com/directory.php
they have a bunch of categories, and it's all free. I found a ton of gift ideas on that sight. One thing I like to make that is cheap and always appreciated for adults is a bathing basket. I usually put in a bath mitt, some washcloths, and some face scrubbies, and a soap saver. I can usually finish a basket in a half day or so. Hope this helps! And happy crafting!
