The Mystic Earth swatch has been uploaded to the yahoo group.
Most swatches are used for gauge. However, for a shawl, I don’t believe gauge is as critical as for a sweater. This is to say that if your shawl is somewhat larger or smaller than mine, it doesn’t matter – it will still be a shawl.
It is still important to swatch, just to make sure that you like the combination of your yarn and your needle size. Things to look for in lace is if you like the difference between the yarn overs (the holes) and the knits (the solid part).
The blocked measurements of my swatch are 15 cm (6”) wide x 10 cm (4”) tall.
