Anael ... a great way to get a well coordinated assortment for a project like NI, for sure! You really scored there!
Those striped prints (there's probably an "official" name for them) have shown up periodically the last few years. In fact, one of my "gifted" DJ blues was one ... but sorry,
W4Me, mine will count as individuals
Sure, I know ... I cheat! :P Only problem is that the stripes are not overly wide, so it limits me to what blocks they can be used. Even though they are only 4-1/2", it;s surprising how much is needed for the pieces. However, I did get a Stonehenge-like one that is broader striped, probably about 4".
I always think these would be a great way to make a TATW without having to buy so many different fabrics.
