Glad you joined in on the Board. Welcome! It is hard to tell sometimes if someone is being critical. Other times, it's very plain. However, your post was not critical, but just questioning how someone can be so fast and have things turn out well. That's a question I've wondered about, too. I measure twice, cut once, and it's still usually off a bit! So when I see TV quilters just whip off something...man, I am jealous of their confidence!
If someone took your post the wrong way...oh well. Keep coming on...it's overall a friendly place to be!
