knitting an afghan pattern on straight needles
Can afghan patterns on circular needles be knitted on straight needles.
It depends. If you can find straight needles long enough to hold all of the stitches, you probably could knit an afghan on straight needles.
But there may be a very good reason that the designer recommends a circular needle that might be unrelated to the number of stitches. Without being able to read through a particular pattern it is difficult to determine whether or not htis is the case.
