I only broke two needles today, and I didn't have to rip out any seams since the mistake I made was something I could live with. I used magenta thread with my dark red bias tape and the stitches are crooked and very beginner-looking, but I've finished the skirt of an apron.
Lessons learned today: no, it's not silly to iron everything, even your pattern pieces and your bias tape; pins are your friends; putting on bias tape in two steps works better for me (especially on curves).
Thanks to April for this wonderful tutorial on attaching bias tape; it's the only one of several I read that actually made sense to me. I'm kind of a sewing dummy—pattern instructions are never clear to me. They'd have to be fifty pages long and be accompanied by detailed photos for me to understand, I think.
Time to retrieve Tiger Lily from her naptime exile.
