I don't know if you noticed but there is a lot of blue fabric being designed, printed, and sold at market, so I can tell you that it's coming your way. By observation, I would say that blue has not been the most popular fabric colour. It's kind of averagely popular. Going forward though, the industry is anticipating a big rush to blue. Several designers have focussed on blue this fall (Jennifer Sampou for one with Shimmer 2). For next year, Alison Glass has done an all indigo version of her beautiful handcrafted fabrics, and The Cotton + Steel gals have done an all blue collection. The best of both will be here soon.
I should also confess that I've chosen navy for all three pictures because I love love love navy. As you may have already noticed. So, if navy is the 2016 colour of the year, I'll be celebrating. If not, I may just crown it on my own.
I don't know if you're planning any blue projects but if you've ever considered it, this will be the season to make it happen.
