I didn't actually check to see whether the size of the templates was different, but since I didn't have to adjust the size of the pattern (which I made to fill the whole canvas) when I copied it to each template, I would guess they ARE all the same size.

But...it's a good thing you mentioned that because I've just remembered that I did actually use the transform tool to scale down the pattern to just cover the template. Not sure why I did that but it might explain the whole problem! I'll have to have another go now. Feeling a bit silly right now! :D

Anyway, for the textures I'm making at the moment there isn't any particular reason why I should use a template as they're not very detailed, so maybe I'll try it with another dress.

I would like to know who made the resources I'm using though! hmm
