Honchey ... heck, I have that problem, just within the blocks for one week! different fabrics/colours/values can give such different looks and dimensions to the same patterns. Personalities, as you say!
GGal ... you have such a nice mix of colours and "moods" ... and they all blend together so well. I'm still really attracted to the pink rose in the first set ... At the Station (I think?) ... and I say I'm not a pink person, and yet lately, pinks seem to be calling to me!
Anael .. Have a good night's sleep!
