- Pins in the mouth, but everyone does it!
- Trying to see by just the tiny light on my machine
- Not pinning things together
- Not following pattern instructions/not marking pattern pieces
- Ironing on the floor
- Sewing/ironing in only bra and panties... I've gotten a few burns and pricks that could have been avoided with clothing
- Ignoring the grain
- Using a seam ripper instead of scissors
I'm sure there are more, but these are just things I've done in the past few weeks.
