Converting to circular pattern

I checked out this book at the library…circa 1986, loved one of the sweaters in there…can I convert this sweater to knitting it in the round?

Hard to say for sure w/out seeing the sweater pattern.

Generally, you use one stitch on each side for seaming, so it would follow you can add the cast on number for the front and back and subtract 4 to get your cast on for knitting circularly.

Other things you may need to take into consideration are any adjustments needed to stitch patterns, etc.

Thanks…I will look forward to doing some investigating in this area once I am a little more experienced in knitting.
I will probably visit my local ys for some help with this.
