I was wondering the same thing. What classifies as an "old" bobbin?

I always close my rotary cutter after using it (my yellow Olfa brand). I like my other one (a blueone, but not sure what the brand is) the one that automatically closes.

I try to always enjoy it. If it has become a huge chore, I start something else and give myself a break from it. Then going back to it makes it fun again.

Simple rules:
1. Enjoy the process
2. Always do the best I can today
3. Learn something new and improve skills with each quilt

I have learned the hard way not to skip details to get done quicker, like not squaring up half square triangles, or not measure borders to fit. I am not a perfectionist, and like to get things done in a hurry, so I have had to train myself to slow down and pay attention to what I am doing. Yes, I am all for enjoying the process, but I also want to be happy with the finished product. So I make sure to pay attention to details as I sew.

My number 1 rule is what ever works!!! LOL

Looks like we have a lot of answers in common!
1. have fun - this rule trumps all others!
2. be fearless - this includes trying new techniques, color combinations, and crazy ideas. Also not being afraid to "waste" the "good" fabric!
3. build with a mind for durability - I always tell people to use, use, USE my quilts!
4. follow my intuition - including deciding when a project needs a major rethinking and/or complete reboot!

Iron to the dark side...

My own first rule, if I am not going to enjoy the process, it isn't going to happen. I absolutely don't do quilts for those who won't appreciate the finished quilt.

If I drop a pin or needle, I stop everything until I find it... no exceptions. Sometimes that involves using a flashlight and wasting alot of time, but I don't want to "find" it the hard way.

My "rule" if you want to call it that, is that I have to be pleased. Personally, I try to do things so that the seams match and the binding is even, quilting is consistent so the batting doesn't bunch and the overall quilt is pleasing TO ME! But if someone else doesn't like to do it that way, then that's fine. I just want to like my end product.
