Let's start sewing the bias skirt pieces together! I'll show you how I do this - along with a few tips and some troubleshooting.
Assembling the Bias Skirt:
- With right sides facing, sew the skirt side seams from the hem up, matching all notches:
I recommend using the flatbed of your machine to do this as it prevents the fabric slipping all over the place.
Stretch the fabric slightly in front of the needle as you sew, so that the finished stitching is not tight. Tight stitching will prevent the side seam dropping, and cause the seams to hang shorter than the CF/CB at the hem.
I like to press the seam allowance so any ripples are flattened, but I don't press the seam open at this stage:
- Check the hang of the skirt on the stand.
If you don't have a dress stand or a helpful friend, you will need to leave this step until the bodice and straps are attached, or you could try pinning it to a slip you are already wearing.
Pin the skirt evenly around the top and examine how the fabric falls naturally. You can already see how the R side wants to curl to the front, and the L side to the back. This is minor though, and within my acceptable limits.
My hem looks fairly level all around - hey, this fabric is behaving! My black version - in the same fabric quality - wasn't nearly as obedient. With most bias skirts I aim to get the hem level to within 1cm - trying to get it 100% level will drive you crazy!
I leave the skirt hanging for 2-3 days like this to let gravity do its thing, before levelling the hem. Usually the CF and CB drop slightly, but any skewed seams will become more obvious too - which is why it it best to sort them out first (see below), so the dropping happens evenly.
- Finish the seam allowances
I usually overlock them together and press them towards the back. Take care when overlocking that you don't stretch the edges and cause excessive waviness - I usually get some minor ripples like this:
...and they should be pressed flat, following the shape of the pattern:
- Now for the hem
My favourite hem finish is a handkerchief hem, so that's what I'll demonstrate here. Turn the hem to the inside as narrowly as you can (about 2-3mm) and edgestitch the fold:
As you sew, try not to stretch the hem - try to keep the fabric in the hem area flat as you sew.
You also need to be careful as you cross the side seams that the fabric is unstretched or you could end up with a kink in the hem.
Press this first fold of the hem to flatten any ripples, and trim away any corners of seam allowance protruding above the raw edge, so the second fold will turn evenly.
Fold the hem up again 2-3mm and stitch around once more, in the line of previous stitching:
You are done - it's that easy!
Bias Skirt Trouble-Shooting:
If skirt does not hang properly it could be due to the following:
- It was not cut on the true bias, ie the grainline arrow was not parallel to the selvedge
- The grainline was not square throughout the piece, this often shows as little disobedient flippy bits at the hem corners!
- the stitching line is too tight, as mentioned above
These three things we can prevent by taking care when cutting and sewing. However the next two are beyond our control, unless you are prepared to do multiple samples. Most home sewers don't have that luxury, so I'll show you what to do instead.
- The fabric weave is not even - I mentioned earlier that most dress fabrics aren't evenweave - usually the lengthwise grain is more dominant. If you study the grain of your bias skirt, the lengthwise grain is pointing upwards at 45 degrees on one side, and downwards 45 degrees on the other side - this can result in the sides dropping by different amounts when they hang. Most often this results in the side seams twisting around the body with a slight curl at the hem. My sample above is doing this to a minor degree, but more severe cases will need to be fixed.
- The skirt is too small - this is very frequently misdiagnosed as too large by the untrained eye! If you are experiencing a horizontal 'bump' or series of bumps down the side seam, then the skirt is too small. It will not feel tight like a straight cut skirt would, but this is the nature of bias cut fabric. A small skirt could be caused from choosing the wrong hip size, or because the fabric has dropped excessively on the bias. When fabric on the bias drops with gravity, it gets longer and narrower - therefore smaller in size. Loosely woven fabrics cut on the bias will drop to a larger extent, and consequently you may need to cut a size larger to get enough finished width in your skirt.
When the fabric weave is causing the side seam to twist, it will look something like this:
Unpick each side seam and let it fall naturally:
If your side seams are unbalanced, the front will drop more than the back, or vice versa. Pin them together so they sit correctly and resew. The notches and hemline won't match but ignore them - and that is about the only time you will ever hear me say ignore notches! For now we pay attention to how the cloth wants to fall instead.
We start sewing the bodice next - exciting - I love seeing how the lace comes together!

How are you proceeding with your Rubies - do you have any questions, and are you getting any pre-Christmas sewing time? I had hoped to have most of the posts up by now, but this time of year is not called The Busy Season for nothing!! I promise to keep on posting as fast as I can write...
