For my own crochet potholders, I use 4-ply cotton yarn,
pounds have been purchased from Peaches-n-Creme Yarn
size 4.5mm crochet hook, which is between a G and an H
foundation begin with 37 chain stitches, but shorter or longer will work
and my own little preference is to grab only the back loop which makes a nice ridge providing friction when picking up a hot dish
I whip stitch the edges together
okay, I found some links, many with pictures
Mielke’s Fiber Arts, LLC/> is the closest to what I crochet
Thrifty Fun this one shows pictures of how to crochet on the hanging loop
Nightly Knitter’s Lotsa Stitches which links back to Mielke’s
if you need more, look up a ‘Net search saying
Crochet Diagonal Potholders
I hope this gets ya going.
I need a nap.
~~love and Huggs, Diane
update Wednesday afternoon: received a phone call asking how much yarn to purchase
Usually, I find that about 2 ounces Peaches-n-Creme cotton makes one potholder, which is what the ombre colors are
a solid ball weighs 2.5 ounces
if using scraps, I just tie a knot and keep working, making sure the knot goes to the back and will be folded inside when finished
