Why would you want to spend the extra time sewing a muslin for patterns? Sewing a muslin is actually a time and money-saving exercise and worth considering for the best fit for new patterns. It is also an opportunity to try out any new techniques involved.

While most of us say ‘sewing a muslin” the French and many designers call it making a ‘toile’ (pronounced twahl).
What is a Muslin?
A muslin or toile is simply a mock-up of the pattern you plan to make. The careful dressmaker will use muslin, calico, or a similar cheap fabric to cut out and fit a new pattern.
The muslin fabric is cut and all pattern markings and seam allowances are transferred from the pattern. It is then assembled into the garment. There is no need for fancy seam finishings or neat sewing since the purpose is simply to try out and fit the pattern.
Sewing a Muslin - Why?
Sewing a muslin test pattern is going to save you time and money in the LONG RUN. This may seem like a contradiction you may think but there are advantages to having a muslin test pattern done.
- You can test the pattern for sizing and any tricky parts of the process before you make up your real garment.
- Using a cheap fabric to get the pattern correct ensures any glitches happen on the cheap fabric and not the expensive material you want to use for the final garment.
- Making a test pattern will also ensure that every time you sew this pattern you have the perfect fit.
Fabrics to Use for Sewing a Muslin
Ideally, the fabrics you buy should be plain with no pattern markings. In saying that, it doesn't really matter if it has a print but generally, plain fabric makes it easier to assess the fit and to mark any alterations on it.
Unbleached calico or muslin is the most commonly used woven fabric but any cheap fabric of a similar weight to your pattern requirement will do.
MONEY SAVING TIP: If you really want to save money then try cutting up old sheets bought cheaply at second-hand shops.
If you are searching for a test fabric for leotards or stretch items, get the cheapest fabric with a similar stretch factor. It will most likely be in a hideous print that no one wants but don't worry as you won't be leaving the house in it. You would laugh at some of the test leotards I've made in the world's ugliest swimwear fabrics.
Sewing a Muslin Pattern that Fits Perfectly?
Step One - Cut the Pattern
Cut out your paper pattern in the size you think will fit you the best. If you range between several sizes, you may want to blend your pattern into several sizes. For example, if you are pear-shaped like me, you may be one size on the top and a larger size on the hips.
Step Two - Transfer Markings
Cut your fabric and transfer all necessary markings – darts, tucks, facings etc. My sewing patterns always include seam allowance, but if your pattern doesn't then add it now.
- Ensure you use the grain of the fabric correctly at this point.
- If there are some areas that may need to have a bit more room added, add some extra seam allowance to make the alterations easier.
Step Four - Quick Sew
Sew the garment together and press all seams. There is no need to neaten the seams as this is just a test pattern. Try out any tricky or unfamiliar additions like collars, sleeves, and waistbands.
Step Five - Alter
Try your garment on and make any alterations. Make a note on the pattern if there are any adjustments to the cutting and stitching lines and voila you have the perfect pattern made to suit your size and shape.

You could try using a double layer of calico or even better would be a cheap wool fabric in a similar thickness.

What about if you want to make a skirt out of a thick wool? What material should I use?
