The shawl took about 70 hours to make. I added the beads by hooking them onto individual stitches as I went along, using a 0.5mm crochet hook. There’s a great article on Knitty.com that demonstrates how to do this (scroll down to ‘hooking beads as you go’). The number of beads on the borders meant that I slowed up considerably towards the end (and in fact only just finished it in time!)
Here’s the shawl after being blocked on a mattress the night before the wedding. I was hugely relieved that it had dried overnight after all that work!
