I don't believe in rules cause they all don't work all the time for everything. So it is whatever works at the time and what I have on hand to work with. My girlfriend is from the school of only one way I drove her nuts. ex. she taught me how to do quillows and I wanted the tying on the other side than she said I had to do and kept flipping it over on me.
She found that I could do it on the side I wanted I just had to stick my hand in the pillow part to get it on that side. It was funny for me at the time but she sure was getting frustrated hahaha. I just said crafts and sewing is up to your own creative juices on your projects LOL
I guess I give her a hard time cause the more frustrated she gets about something the more I get the giggles can help it she reminds me of I love lucy sometime. Lets admit it lucy was funny.LOL
