Drats! Foiled Again!

Ok. These Gryffindor socks are out to get me! I worked the leg on both socks, turned the heel & started the foot on one. It was looking kinda small so I tried it on. Well... I attempted to try it on. I couldn't get the dang thing over my heel. Now, Avada's feet are a little smaller than mine but not much. If I can't get it over my heel, the likelihood is that she won't be able to either.

Now I have a dilemma. I really like this pattern...
but the number of stitches is not adaptable. The yarn I have needs to be knit on size 1 needles or smaller. In order to use this pattern I will need to find a different yarn that can work on size 2+ needles. I actually have some Lorna's Laces that would be perfect but they were picked out by Autumn especially to be knit into socks for her. I think she would hurt me if the yarn was misappropriated.

So, do I search for a different yarn? Or do I go on yet another pattern search in order to use the yarn I already have? Input is desired and the cats are no help!

UPDATE: I have just purchased yarn that I think will do quite nicely for this project and should allow me to up the needle size! Now I just need to wait for it to arrive! I guess I will just have to cast-on something else to knit in the meantime.
