With all of the cookies crocheted and the ends woven in, the only thing left to do was join them in some fashion.
Using Red Heart Super Saver warm brown, I worked a join not unlike the join I used in the original cookieghan:

It looked great, but about 5 cookies in, I realized that the join was a bit less fluid and forgiving than what was needed for a scarf, so I took some of the cookies that had not yet been joined and tried a variation on my first effort:

This joining resulted in a drape that was more hospitable to wearing as a scarf, so I continued on my merry crochet way, and by this morning, I had gotten this far:

Then with bent-tipped yarn needle in hand, I wove in ends. First one, then another. Finally they were all woven in, but the edge was a bit floppy, so filled in the border with sc stitches. When it still wasn’t holding together the shape as I wanted it too, so I continued and crocheted a round of slip stitches, and then it looked to my eye, just right:

Here is the long view:

and here it is chillaxing on the front porch the afternoon after the fall’s first hard freeze:

Now that I have this cookie scarf done, I have an idea for another completely different join for a second cookie scarf, but I am going to wait to see what project strikes me next, and if you are looking for your next project, you might want to consider joining a crochet-along featuring Lianka Azulay’s crocodile fingerless glove pattern and using her exquisite yarn. It might just be what you need to unleash your crochet mojo.
