I read a lot of posts that indicate problems with FMQ and saying something like "this is my first try at FMQ".
It takes practice and more practice to do it easily. You note I didn't say best or correct or right.
There is a motion skill that must be learned by each qulter. So many sad stories that imply that only thing needed is a quilt and a machine that the feed dogs drop.
Please do practice pieces, read about it, watch the videos and if at all possible take a class. I don't believe it is something one an do just by pushing the quilt around under the needle. And then please when a question is ask, give all the details. A statement like "I have my quilt sandwiched and rady to FMQ, my thread is tangling" is not enough info to give an informed answer.
Just had to write this today because I read so much frustration and pain in some of the posts about FMQ.
