I'm learning more about the value of muslins by experience. A muslin is a test garment: it's purpose is to fit the garment to the wearer--it's not meant to be worn as "real clothing." I don't like the idea of making muslins, because it's "extra work." Well, I have learned that if I don't make a muslin, the first version of the garment is a toile by default.
I have made two versions of Simplicity 3696, the drawstring pants. The first pair is by default, a muslin. I sewed them wonderfully, but the fit was off. Even though I pin-fit the pattern paper, the finished project was too loose and baggy--they resembled pajamas, and are not suitable for work and are destined to Goodwill. In the next version, made from the same fabric (a solid color seersucker with a crosswise stretch), I took in the outside seam from the waist to the knees (in the next version, I just might cut the pattern to the smaller size on the outside seam). The difference in the fit is amazing. The waist is about 2 inches smaller, so there is less fabric bunching up on the drawstring belt, and my waist is now visible. I'll try to take some pictures and add them sometime tomorrow, so you can see the difference. The second pair, dark navy blue, are suitable for work.
I'm also revisiting the Burda World of Fashion Pants 09-2005-129. I tried making this earlier this year (without a muslin), but the fit was off. Way off. I just bagged up everthing and set it aside. I pulled this UFO (Un Finished Object) out of a pile and took a closer look at them. After I tried them on I could see that I needed to lengthen the crotch (front and back--I had to do this on Simplicity 3880, and 3696 and the wrinkles seemed to indicate this alteration). So I altered the pattern, pin fit it and it seemed better. Well, as good as swedish tracing paper can look taped together (I trace BWOF patterns without the seam allowance). And then I couldn't find any suitable muslin fabric in my stash. I swear, sometimes it's like dying of thirst while floating on a raft in the middle of the ocean.
This past weekend there was an estate sale in my hometown. Since I'm cleared for driving, I decided to attend. The estate belonged to a tailor's family and there was lots of housewares and furniture. I, of course, headed directly to the sewing area. The buttons had been picked over, but I was able to get two bolts of fabric, one of which I can use for muslins. It's a really nice creamy white cotton sateen (with a very similar hand/feel to the Catherine Ogust fabrics I got from an online coop). It might be upholstery weight (it's non-stretch, 54 inches wide) and it's almost too nice for muslins.
But I bit the bullet, measured off 2 and a half yards and cut a muslin of the BWOF-09-2009-129 pants. I was able to sew them up (no topstitching except for the front pockets, rudimentary darts, no seam finishes, unhemmed and without a zipper in the fly. Hey! it's a muslin) in less than an hour. And they fit pretty darn well. I need to lengthen the hem by about an inch so I have more freedom for alterations. Even though the muslin isn't suitable for wearing outside the workroom it looks much better than the first version which is more finished (with topstitching, installed fly zipper, etc). I'll save the muslin so that I can use it to play around with adding/fitting the waistband. I'm coming to realize that it's not extra work to make a muslin.
