This past weekend I bought some elastic cord, and threaded three pieces through the ribbing on the Bobbled Tam (aka Afterbirth Hat). It fits!
Edited 4/11/09 to add photos & delete rant caused by Blogger failure to upload pics the first time I tried it.
And now I seem to have lost contact with Blogger. Of course! This may be why I blog only once in a while, since there's only so much aggravation I can take.
