How to knit a Haapsalu Sall

A Haapsalu Sall is a title for a lace shawl or scarf in Estonia. Made with openwork lace patterns.  If there is a lacy edge it is always knitted separately and sewn to the completed center section by hand.  A newer style of construction is to pick up and knit the lace edge onto the completed shawl center.  I'm planning to knit the nontraditional style by picking up and knitting the lace edge.  The pattern is called Queen Silvia Shawl and was named for Queen Silvia of Sweden.  It is a variation of the lily of the Valley motif.
I purchased 1/2 pound if white merino top that is 19.5 micron from Rose Haven Farm in Picton and have spun and plyed about 1000 yards semi worsted.  24 wpi. The pattern calls for 1300 yards so I plan to spin as needed because with the first ball of 350 yards, I've completed 9 repeats of the pattern so I am wondering if I will need as much as the pattern calls for. 
 I used cotton waste yarn and a crochet hook to cast on 117 stitches and began knitting the center portion of the shawl.  That was three weeks ago and thus far I have only knit 9 repeats of this 20 repeat center section.  Although I  have to add here, that I have really knit about 14 repeats because I've had to rip back to my safety lines a couple of times.
It's not that the nupps are hard to knit, this video:  is an excellent how to, but I seem to be dropping stitches somehow and I can't figure out how I am doing that.  It is very difficult to fix mistakes, without making more mistakes, that's why safety lines are a must.  I found this video to help explain safety lines.
Guess I'll keep plugging along/muddling thru, and longing for the end result.  That's what knitting is all about.  Soldier on!!!

Next time knit the nupps

I think I might be addicted to knitting lace shawls. This Swallowtail lace shawl is my third shawl or shawlette since January and I can't wait to try another one.   Each one teaches me something new, well new to me anyway!.. With this shawl I learned about safety lines.  This shawl was knit over three times before I remembered about the safety line.  I used two safety lines with this knit, always taking out the bottom and putting it back into the top or the current working pattern.  This way when a mistake is made and not noticed I will alway have a safety line to go back to.  And the blocking! what a wonderful idea, who knew!! 

 I left out the nupps because my knitting is way too tight and doing a K1, YO, K1, YO  all in one stitch isn't too bad, it's the purling 4 stitches together in the next row that get me every time.  So I used beads instead of the nupps.  Using the super dental floss methed to insert instead of the nupps.  But next time I would try a bit harder to knit the nupps especially after watching this : video
