Back in 2005 I published a knitting pattern on my blog that was inspired by a pattern called 'Birch' designed by Sharon Miller. But instead of being worked from the top down with 300 and some stitches to be cast on my shawl was worked bottom up. No more miscounting while trying to get slippery Mohair yarn to behave. No more running out of yarn. Just knitting until the shawl is as large as you want it to be. Since then the pattern became known as 'Bottom-up Birch'.
The instructions were very basic though and the charts not very pretty. Since people are still asking for clarifications and according to the Ravelry database the pattern is still quite popular it was high time for a revision of the pattern. I managed to make up the pattern in a prettier form with nicer charts and hopefully better explanations. On top of that the pattern now contains also an asymmetrical version that's knitted sideways. The new format also called for a new name - Birch Leaf Shawl.
