Waving Lace WIP

I'm working on my next sock, Waving Lace Socks by Evelyn Clark.  These are from the same pattern as the socks on the cover of Interweave's Favorite Socks .  I like the design but I find that mine are not turning out quite like the pink socks in the book.  For the lace pattern the eyelets in one direction are made with a yarn over after a purl and before a knit. The eyelets slanting in the other direction are made with a yarn over after a knit and before a purl.  I find that the latter eyelets are larger than the others because I have to wrap the yarn all the way around the needle before the next stitch. I know it is not a big deal but the socks on the cover of the book have that nice zig zag line of eyelets that I am just not achieving here. I do like the wavy ridge design when they are not stretched.I have to remind myself that they are just socks. As my grandmother would say, "No one will notice from a galloping horse..."Does anyone else have this problem with eyelets?
