My neighbor has a pattern for a gorgeous baby sweater that zips up the back and has the cutest little hood, but the pattern is only for 6m. We want to make it for our 2 big ol babes that can wear around 18-24mo sizes. What is the best way to make the pattern bigger? Should we alter the pattern and increase everything which is kinda confusing or could we use bigger needles and thicker yarn? <img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/orngtongue.gif" style="border:0px solid;" title="Stick Out Tongue">Yes, I will ask her to post the pattern, it is sooooo cute!!!!!!!!!!!!!!!
