Sewing jeans: Muslin 3

Before I show you what muslin 3 looks like I first want to show how I adapted muslin 2 into muslin 2.1 to determine how to change the pattern.

I started with a very simple alteration. Muslin 2 showed a lot of fabric being pulled into the crotch indicating the crotch length was not long enough. The trousers were also very tight across my thighs indicating I needed some more room there. I solved both issues by doing what “The Perfect Fit” one of the fitting books I own, calls a full thigh adjustment. The pattern is extended both at the side- and inseam which lengthens the crotch seam and increases thigh circumference. The red lines in the schematic below indicate how I re-sewed the seams in muslin 2 and changed the pattern for muslin 3. I also removed the gaping I had at the yoke.

These 2 changes already made a huge difference to the fit as you can see below.

Muslin 2.1 front

Notice how the straight of grain lines have become much straighter and more horizontal.

 

Muslin 2.1 back

Wrinkles at the knee have disappeared. Straight of grain lines are straighter and more horizontal. Yoke lies nicely against my back. It no longer looks like I am about to burst out of these.

Muslin 2.1 Side

Wrinkles at the knee have mostly disappeared. Side seam has become straighter. There appears to be less strain on the fabic on my butt.

After I changed this I noticed I could remove some of the wrinkles I still had at the front by pinning out 2 darts. I made this alteration in the pattern by slicing the pattern open and overlapping the edges to simulate the dart I had pinned out. This does not change the side seam.

At the back I thought I probably still needed to add some more length to the crotch seam so I sliced the muslin open horizontally and inserted some fabric. This did seem to improve the fit at the back and the muslin became more comfortable to wear so I made this alteration in the pattern as well. This is done by slicing the pattern open and creating a hinge point at the side seam. You can then add a wedge to the pattern by sliding the center back upwards. The side seam does not change.

adjustment to back

After I had made all these changes I decided it was time to make muslin 3 to check whether the changes I made on the pattern were correct. Unfortunately I ran out of muslin fabric (why did I ever think 3 meters would be enough???) and had to use something a bit lighter weight than ideal but I didn’t want to wait until I had the opportunity to get some new fabric. The fit is still not perfect but I think you’ll agree this is definitely an improvement over where I started with muslin 2!

Muslin 3 front

Still not 100% happy with the crotch, but overall I don’t think this looks too bad. Side seam at the thigh is perhaps still a bit too much to the front.

 

I still need to add more lenght to the back crotch lenght because fabric is still being pulled in. My alterations at center back caused the center back seam to be a bit strangely shaped so I'll need to reshape it.

Muslin 3 side

Side seam still not completely straight. Center back seam sticks out.

How many muslins do you think I’ll end up making before I dare cut into my denim?

Sewing jeans: Muslin 2

If you are now wondering whether you missed a post about muslin 1. You didn’t. I had originally planned to blog the whole fitting process but muslin 1 was unfortunately not suitable for public display due to indecent exposure of underwear.

I am attempting to sew myself a pair of well-fitting jeans. I’ve wanted to do so for years because I am never completely happy with the fit of RTW jeans, yet jeans are what I wear most days. In summer I am a jeans and t-shirt girl, the rest of the year I’m a jeans, t-shirt and cardigan girl. With my RTW fast the need to finally make these self-made jeans happen is getting more urgent. Sewbusylizzy organised a Jeans in June and July challenge and this was the final push I needed to get started. Not sure whether I’ll actually manage to finish an actual pair in July since August is already looming on the horizon and I have to work all remaining July days except for today but if I finish the muslin process in July I’m happy (and if not, I’m probably still happy).

I already had a pair of jeans stashed away that I had started copying using the method from Kenneth D. Kings Craftsy class. I started that project ages ago but got distracted and was also a bit scared to continue because my first ever attempt at trousers years ago failed horribly and caused a bit of a trauma.

Tracing pattern onto silk organza

copying jeans

The original jeans were copied by thread tracing the seams and straight of grain lines and then transferring these markings to silk organza. If you want to get a better idea of how this method works have a look at this post by Cindy from cationdesigns, she posted about this process in more detail earlier this week. The pattern was then transferred from silk organza onto Swedish tracing paper (my favourite type of tracing paper ever). The pattern was trued (which means making sure that all seams have the correct shape and that seams that are supposed to match up, do in fact match up) and I made a muslin. I made my muslin using regular muslin fabric without stretch, because this is what Angela Wolff recommends even if your fashion fabric contains lycra. I’m really hoping this will work out ok when I do sew my final pair in denim that contains some lycra and is, therefore, somewhat stretchy…

Anyway, as you may have guessed after reading the first paragraph of this post, they did not fit. In fact, they were super tight and couldn’t close (to be honest the original jeans are also a bit on the tight side). I made 3 changes to the pattern. 1. An adjustment for full inner thighs. 2. More room at center back. 3. More room at side seam of back. I probably could have tried to change more but worried that it would get so messy that transferring my changes to the pattern would become a nightmare.

After making these changes to the pattern I made muslin 2 from the same muslin fabric hoping I would now have something approaching wearable. Note that this muslin does not yet have a waistband. I’ve used waxed tracing paper to indicate the straight of grain lines. I’ve also added some horizontal lines that help to diagnose fit issues. These are definitely not the most flattering pictures I have ever posted of myself but I think I am now at a point that it seems likely I can get to a fitting pair at some point. Remember, it’s always the garment that is causing the horrible fit, your body is just fine! After all, I can change the garment to adjust for my shape but I can hardly adjust my shape to fit the garment. Well, I suppose I could get a surgeon to shave some flesh of my thighs but that doesn’t really seem like a workable approach to use for each new garment I want to make…

Muslin front

Do you notice how the fabric is pulled into the crotch causing distortions?

Muslin back

Again fabric is pulled into the crotch. It’s also pulled towards the sides. I will also need to change the placement of the back pockets at the end of the process to make sure they end up more centered.

muslin sides

Eventually the side seam should end up perpendicular to the floor. Right now there is too much strain because fabric is being pulled to areas where there isn’t enough fabric causing a wave-like shape

Obviously they are still too tight but at least I can close them now. I believe most of the issues are caused by a too short crotch length that is causing the fabric to be pulled into the crotch both at the front and back. I think I will also need to add some more room in the thigh area as they are still very tight. My previous adjustments at center back now causes some gaping at the yoke (something I nearly always get in RTW jeans) so I’ll fix that too.

Do you have any other suggestions for adjustments that I could make to get a better fit?
