Mutiples of 4 + 1

[mellon]

What does this mean? I am making a sweater and the directions are given for a pattern stitch (Multiples of 4 + 1) Does anyone know what this means, please?
Thanks!

It means that your cast on number will be a multiple of 4, plus one extra stitch. Each stitch pattern has its own little formula like that.

Does the pattern tell you how many stitches to cast on??

basically you start with whatever multiple of 4 you want...4,8,16,20, etc and then add 1 to it and that is your cast on number...so 5,8,17,21, etc
