I don't know why I haven't purchased these cool tools until now -
but HOLY COW! (Yeah - I'm from Utah) I love them! I have always figured out my thread tension by just feeling the pull on the bobbin case, but lately that hasn't been working. I don't know if it is because of my new rotary hook or not, but now I won't live without a TOWA bobbin tension gauge. I got mine at Superior Threads for $67.95, pretty good deal - plus I live close to Superior - so I didn't have to wait for it to be shipped to me. There are two styles - so make sure you get the right one. For my A-1 it's a M-style gauge.
Okay - I-pod shuffle - totally necessary to block out the noise and distractions (I create my own distractions) during my few hours of quilting while the kids are sleeping. I also use the I-pod to go running.
So - now I am totally committed to these tools - won't live without them - and I am also committed to running this. I have registered and everything - 20 weeks to become strong enough to do it. Wish me luck!
