I am making coasters with the pattern that is posted on this site. The directions say to use five dpns, dividing 8 CO stitches between four needles. Is there any reason that I couldn’t use four needles instead? Do you have to have the same number of stitches on each needle? I can’t see any logical reason why it wouldn’t work with either 4 or 5 needles, but I am a beginner so I really don’t know!
