I queried "modern quilt guilds" in Pinterest this afternoon and discovered that 30 guilds have Pinterest sites. Each of those sites have various board and many pins. There are a few guilds who are just starting their sites and fewer than 15 pins, but some have as many several hundred to a thousand. If you are interested in modern quilts, fabrics and guilds, you might consider using Pinterest.
One of the themes I noticed as I looked through several of the guild sites is the use of circles.
