The Trinity Shawlette pattern can be found on Ravelry (you must have an account to login). There are three versions of the knitted lace shawlette pattern, so after you complete one, you can begin another!
When I knitted this shawl, the pattern was free to those who gave to Medicine Sans Frontiere – the leading non-governmental organization (UK chapter) for emergency medical aid. Check to see if that still applies. You can knit something beautiful and contribute to a great cause.
