Patons Stretch Sock Yarn

I just bought some of this yarn because I wanted to try to tackle “THE SOCK”.:happydance: My only question is that since it is a stretchy yarn and the pattern says to cast on loosely, should I not cast on so loosely? Considering the yarn already has stretchiness in it.

Thanks in advance!!!

No, you should still cast on loosely; even though it has 7% elastic in it it is still mainly made up of cotton, wool, and nylon. Also, you do not want to over stretch the elastic that could put more stress on it than you would like or need causing it to stretch out faster.
