I have often wondered this. And to own the truth, I always just end up throwing them away. And then I when I come back to a pattern to remake it, I wonder why I did that. And then I remember that I'm NOT a pack rat and I don't really have alot of room for all these muslins.
With these pants though, I'm feeling differently. I WILL be keeping these puppies. The interesting thing I've learned with fitting and alterations and muslins is that its such an ongoing process. I don't know that my body really changes drastically from year to year, but I do notice that it changes. I also notice that my ideas on good fit change too. I'm constantly seeing new things crop up on previous garments that I've made that I didn't notice before; that I wasn't even aware of; things that throw the fit off and would have been relatively easy fixes if I had known what to look for and how to fix it. Does this happen to you? Do you ever feel this way?
What do you normally do with your muslins? Do you keep them or get rid of them when you're supposedly finished with them? If you do keep them, do you find them useful the next time you make up the same pattern or do you end up making another muslin anyway?
Next up - January 24 - the beginning of final trouser construction! We're almost there! Hip Hip Hooray!
