Ohhh....No.....I'm out of yarn

Instead of reducing my crochet yarn stash, I actually need to increase it, what a pity. This happen when I'm out of yarn for red heart sampler Hi-Fi set. I've crocheted 7 squares (6 + 1 99% finished) but there are not enough, I need at least 12 squares!! Ohh....no....I got to buy the same colour shade yarn, hopefully the LYS still carried this colour shade in their store, cross my finger. The colour seem too bright, anyway, that's doesn't matter much, since the Hi-Fi set is in black colour, they will accomplish each other in the colourway.
