nothing much intimidates me when it comes to machine sewing, - but I just don't care to spend hours doing hand sewing work. I'm more likely to not do a pattern because I think I'll get lost in the tediousness. I also like to see progress, so it's hard to work on something that there is a lot of time spent for not much return.
Maybe once I'm retired I'll feel better about doing something that is going to take a lot of time. I'd love to do a La Pasacaglia quilt some day.
