Link to links of tangle patterns.
While poking around searching for new zentangles--something I haven't spent enough time on lately-I discovered Geneviève Crabe's (aka AmaryllisCreation) Wordpress blog, Zentangle Harmony. She's got a weekly round-up of tangles she's found--including a few that I missed, so be sure to check them out. If you haven't already discovered her tangles, keep searching through the blog. She's got several posted there. It's an interesting blog.
