I've lost track of how many I've joined in the last ten or so years: I'd guess at least seven ..... maybe ten.
This Board is HUGE compared to any other board I've ever been on. I'm on here every day.
APQS I almost stopped visiting after they totally changed how the board was designed and I found it difficult to keep track of what I was interested in reading. Still occasionally check in, though. They have some lovely FMQ-ing eye candy.
MQResource I joined not long ago: I like it. It's a wonderful resource ~grin~ for FMQ ideas and eye candy.
But The Quilting Board is my "home" ~ as some have mentioned, the response time is almost instantaneous. And there's almost always several (or many) different takes on answering questions. There's a huge variety in the quilts shown and I've learned some very, very useful tips & tricks.
With that said: MAHALO to all the members of this Board for making it such a wonderful place to come.
