You will need:
• H (5.0 mm) Crochet Hook
• Cotton Worsted Weight Yarn (way less than 1 skein)
• Tapestry Needle (for weaving in ends)
• Wine Glass (mine had 2 3/4" diameter base)
Chain 20 and join with slip stitch to first chain, forming a loop. Check to make sure it will just slip around the base of your wine glass. If not, adjust your loop by adding/subtracting chains in 2's. You want your loop to have an even number of chains.
Chain 1, then single crochet (sc) around in each chain. Slip stitch (sl st) to first stitch to join.
Chain 4, skip a stitch (sk st), then slip stitch into next stitch. Continue *ch 4, sk st, sl st* all the way around your chain loop.
After your last chain 4, skip a stitch, join with a slip stitch in same stitch as first stitch in the round. It will look like a flower with 10 petals (more or less petals if you added/subtracted chains to adjust the size of your original loop).
Chain 4, slip stitch into the 1st chain 4 space from previous round.
Continue *chain 4, slip stitch into next chain 4 space* around. You will now work in a continuous spiral, without joining at the end of each round, until your "net sleeve" is almost as tall as you want it. It will start looking less like a flower and more like a wine glass sleeve! Mine was about 6 spiral rounds after completing the original 10 "petals."
At this point, it is a good idea to try the sleeve on your wine glass. Remember that the yarn will stretch a bit once your glass is full of vino, so leave some sipping space on top! The "net" crochet stitches are fairly forgiving and stretchy, so your sleeve should fit both traditional and chunkier glasses. If it doesn't fit the way you want, just go back and add some chains at the beginning. The sleeves work up so quickly that you hardly mind frogging and starting over! Once you're happy with the fit of your sleeve, it's time to add some substance to the top.
Chain 1, single crochet 3 times into same chain 4 space. Then continue *single crochet 3 times into chain 4 space* all the way around the previous round. When you reach the end, slip stitch into the first single crochet from the round to join. Congratulations! The sleeve portion is done! Try it on your glass one more time, but don't cut your yarn. Now it's time to make the neck strap.
Chain 80 somewhat loosely. Loop the chain around your neck and add/subtract chains until you've got the length you want. Make sure your chain is not twisted and slip stitch into opposite side of sleeve. I counted 12 stitches backwards (to the right) and slip stitched into the 13th stitch. You will need to adjust if you started with more/less "petals" at the beginning.
Slip stitch in the next stitch. Then single crochet in each chain of your strap all the way back to the beginning of your chain. Slip stitch into stitch next to beginning of chain, then slip stitch again in the next stitch. Single crochet back to the other side of your strap one more time. Slip stitch one more time and tie off to secure your strap. Finish your wine glass holder by weaving in yarn ends with a tapestry needle.
Voila! You now have a ridiculously silly wine glass holder with neck strap! I'm pretty sure if I ever actually wear mine with a full glass of wine, I will end up with a very wet top, but am looking forward to sharing giggles with my book club buddies. ;)
