Here's what I used: yard sale sweater, scissors, small glass fish bowl/round vase from Goodwill, needle and thread.
Begin by cutting off the turtleneck.
Insert the glass bowl into the newly created tube with the finished edge around the top of the vase. Make a running stitch using same color of thread around the bottom edge of the tube to "cinch" it in to the bottom of the bowl. (You could probably glue it to the bowl for a more permanent solution, but I wanted to keep my options open.)
Make another running stitch around the top to draw the knitted tube in to the glass, eliminating any gaps.
As you can see, my In Between Mantel is getting slowly tweaked into it's fall glory. I found this cute little squirrel at Hobby Lobby a couple weeks ago and he has been perched on the mantel waiting for more fall splendor ever since. I love everything about fall and have a hard time waiting to decorate for it...not that I want to rush the seasons along, but I just can't get enough of the rich colors and aromas of Autumn. Who's with me? Have you started putting fall touches around your house?
