Thanks to Dorothy's suggestion of a pom-pom, and Patsy's suggestion of I-Cord, the turquoise hat now has this cute little topper. I added some brown yarn to the pom-pom just to give it a more little pizzaz, what do you think?
My Knit Happy Sto N Go Knitting Project Yarn Box Case arrived and I love it even more than I thought I would. It fits all my afghan yarn and squares easily with a little room to spare and I love, love, love the front exterior pocket which is the perfect place to store the afghan pattern. This is a well-made product (and nowadays it's so hard to find good quality items, don't you find?). Full, it can sit by a chair or on a bookshelf or in the closet etc. and when it's empty the whole thing collapses flat so you could store it just about anywhere.
Turns out Duke thinks it's "just perfect" for sitting on too (at least when full of nice squishy yarn). But hey, with the zippered top it keeps my afghan yarn dust and dog-hair free!
