Julia let me know recently that a short tutorial/explanation might be helpful for some people who are having difficulty starting their Charlotte's Web shawls.  Hopefully this will help those people out.  This is really an explanation of how I approached the pattern, and what worked for me.
 
 
Color #1 (Rows 1-26)
1) Cast on 7 stitches
 
2) Knit the first 10 rows of the chart.  These make up the foundation for the lace pattern stitches.
 
3)  Knit rows 11-26 as per the chart, using stitch makers to mark off the begining and end of the 8 stitches lace pattern. These 16 rows are the pattern for the entire shawl.
 
When you are done with row 26, you will notice that you have enough stitches on either side of your makers to add another 8 stitch lace pattern. 
 
Color #1 & 2 (Rows 27-42)
1)  Row 27 - 42 are really just the same as rows 11-26.  All you need to do is add 2 new 8 stitch lace paterns to either side of the shawl.  Where in rows 11 -26 you worked the lace pattern once on either side of the shawl, in rows 27-42 you work it 3 times on either side of the shawl.  Nothing else changes from those rows.  The begining, end and center of the rows are knit exactly the same.
 
I typed out the directions to rows 11 & 27 to give a better example of what I mean.  I did not type out the 8 stitch lace pattern.  Check out your pattern for that. 
 
The K1 in bold is the center stitch.
LACE1= the first row of the 8 stitch lace pattern
RLACE1= the first row  of the 8 stitch lace pattern in reverse
YO = yarn over
K = Knit
 
Row 11:   K2, YO, LACE 1, K1, YO, K1, YO, K1, RLACE 1, YO, K2
Row 27: K2, YO, LACE 1, LACE 1, LACE 1, K1, YO, K1, YO, K1, RLACE 1, RLACE 1, RLACE 1, YO, K2
 
Color #2 (Rows 43-58) and all subsequent sets of 16 rows
Once again these rows are the same as rows 11-26, just add another 2 new lace patterns to either side of the shawl.
 
And that's it!  Every 16 rows when you change your color, just add another 2 new lace patterns to either side of the shawl.  It's really very simple once you realize you are really only working with the same 16 rows repeated 9 times.  The more lace patterns you add into the shawl, the more important those stitch markers become.  I made it to about row 50 before adding them, and now I don't know what I was thinking working without them.
 
I hope this helps, if anyone has any questions I could possible answer just send me an email, or leave a comment.  Once you work those 16 rows a few times it really becomes second nature.
 
*New* added 6/3/04
This is some added explanation on using the stitch markers I wrote up in response to some questions that people e-mailed me about.  I hope this helps clarify what I wrote above.
 
I found the key to adding the stitch markers was this: you never have to move the ones you already have placed.  (Other than slipping them as you knit).  I found the key to adding the stitch markers was this: you never have to move the ones you already have placed.  (Other than slipping them as you knit). 

Every time you start a new set of 16 rows do the
following:
*Knit 2
*yarn over
*Add Stitch marker
*Add new 8 stitch lace pattern
*Work the 8 stitch lace patterns you already have
marked with stitch markers.  Just slip the markers as
you come to them, as you would slip a stitch.
*When you get to the last stich marker before the
center stitch of your shawl, slip it and then add a
new 8 stich lace pattern. 
*add a stich marker
*Knit 1
*yarn over
*Knit 1 (the center stitch)
*yarn over
*Knit 1
*place stitch marker
*add 8 stitch reverse lace pattern
*work the patterns that you already have marked off,
slipping the markers as you come to them.
*when you reach the last marker at the end of the row,
slip it, and add a new 8 stich reverse lace pattern
*add a new marker
*yarn over
*knit 2


You now have your new patterns added.  It's exactly the same as row 11, you just have more lace patterns in it.  Your next 15 rows get worked just like rows
12-26.  When you go to start another set of 16 rows, just add the place markers the same way.  You never need to move the ones you already have.
