For Larger blankets: per Charity on Facebook, "Here is a beautiful one that used 80 pegs on the AIO (All-n-One). It took her 8 wedges. It turned out to be 42.5 inches across. You can find out how large it will be now by measuring your cast on row and doubling that length. www.ravelry.com/projects/Castafiorisa/hexagon-baby-blanket
" ....My guess/calculations is if you used all the pegs on the AIO that your blanket would be about 56" which would be very large. It might make 8 wedges though so not a hexagon but very nice anyhow. You'll just have to see.
I'm told a 3/4" gauge loom in 72 pegs will make a blanket about 60". They used a Martha Steward loom with every other hole used.
