@Luvy: It wasn't really any harder than the others, but I made sure to get the Perler brand mini tweezers to do them with. I think without those it would be nearly impossible! It was super fun and rewarding, I love being able to get all that detail in there without having the piece end up really huge. They've also melted really evenly when ironing them so far. I'm going to upload a side-by-side picture now of the same piece in regular and mini so you can see just how small they are!! (And I also got a good price on everything at Michael's because they have so many coupons!)
