The hole is no more.
While it may seem like I was procrastinating, I was thinking about it a lot; going over the stitch pattern in my mind. Occasionally I would even go and look at it. What threw me was not the stitches themselves, I could see where they went; it was the big loops of yarn I had that were supposed to be a complex pattern of 'bars' holding the leaf pattern together.
I just couldn't figure out how it all went together - especially the two long loops running parallel to the leaf! The hole got worse than this photo shows as I desperately tried to find where each strand belonged! I should have taken another photo before I began the repairs but that didn't occur to me.
Although I finished the repair this morning, I had been working on it for two days - I picked up the dropped stitches that I could see and yesterday I had a couple of tries to put it together but it wasn't working. More thinking, not procrastination, was needed; the shawl had given me too much trouble to rush in and do a bodgie* job.
So, here it is; I'm sure you won't have any trouble picking the repaired leaf but it's not too bad, if I do say so myself!
Thanks for the support and encouragement; it really means a lot to this often-close-to-tears-soon-to-be-mother-of-the-bride!
And now, we're off the reblock the border to our satisfaction [DD and I not the royal 'we'!]
