I bought the biggest size of this and I'm glad that I did, but I have 2 complaints. 1 - there are 3 different colors of red used. 2 of the 3 are a 6 and an S. Its super hard to tell them apart, but I think I've done alright (I'm about half of the way through right now). 2- I dont get why one of the butterflies is red. There's so much red in the picture that they should've picked a different color for the butterfly. The other one is green and yellow so I think I'm going to buy another pack of green diamonds and change the red one to match the other one. Otherwise I love it and cant wait for it to be finished!
