Due to multiple requests for this pattern, I have decided to get off my lazy patoosky and post it for you.
(I would say these are by me, but I got the pattern from my grandma eons ago)
With Chunky or Bulky yarn & size I/J hook
1- sc in 2nd ch from hook and each ch across (25), work down opposite side of ch (do not increase in the corner) put a sc in each ch across. do not join (50 total sc)
Then continue to work in each sc around until the square begins to fold in on itself forming a 'hotpad'. (It will look like a bag or pouch by now).This will be about 10 rows for the chunky/bulky yarn. On one end I chain 6 to form a loop to hang it with. This is completely optional. Then when the edges meet together nicely without puckering or pulling..I simply whipstitch the edge together and Voila! you have a potholder!
Potholder/Hotpad with WW yarn & G/H hook.
1- sc in 2nd ch from hook and each ch across (35), working on the opposite side of the ch (do not increase in the corner) sc in each ch. do not join. (70 total sc).
Then repeat as for the Bulky/chunky pattern. This will go for approx 30-35 rows. It always ends up different for me..(don't ask me why..but it is the bane of my existence) Do the same for the loop and assembly.
It really is the easiest pattern. Just remember the edges need to fold in towards each other. If you are sewing it together in a big square...it's not wrong...it's just not this pattern. :)
