Why does a seam allowance need to be considered




















I just hate it! I find it bulky and cumbersome. A hem typically has two turns. I said typically , of course there are exceptions…. But, I digress…a hem will have a different amount of seam allowance depending on what type of garment is being drafted. This not only creates weight and a nice swing in the sweep…but, it also allows for alterations in length.

How about a pencil skirt. Lastly, there are also other things…like stuff you might attach to a garment. Like a zipper or a patch pocket. All of these will vary depending on the width of the zipper tape, the type of pocket. All exceptions to the nonexistent rule!

What do you do about this? I am in tge process of teaching myself pattern drafting and have one question. You mention to draft without seam allowances and when finished with fitting and alteratioms, then you add seam allowances afterwards. What about ifnyou are sewing up a toile or muslin. I am having problems with a neckline in that it is too small when i sew up the shoulders. If your seam allowance either falls short or extends too far, go back and reposition to either add or remove a stitch.

With practice, you will become acclimated to the distance and can quickly eyeball when to stop and turn the fabric. Another feature marked along seam allowances is the notch. Notches are the best method of fitting pattern pieces together that tend to curve such as sleeves and crotch lines. For the fit to work where fabric is shaped for the body, notches help to keep things aligned. The pattern has these notches, which you can transfer onto the fabric. I have advanced from chalking them as outward notches to making a tiny v-cut that goes inward along with the seam allowance.

I make these notches in the fabric as I cut out my pattern pieces. When matching these notches that act as road signs to their corresponding mates, you can be sure your sleeves will meet adequately end to end without ending up with one piece longer than the other. Ignore these handy little markers to your peril. These notches are how your garment will fit together and fit the body for the necessary ease of movement.

Following these technical features will help you spend less time with your stitch ripper. Your great reward comes when you or your subject try on the garment for fit and everything looks and feels good.

That depends on what kind of project that you are sewing. It's also important for fabrics that unravel easily. Finally, it also provides a small amount of adjustment space if a garment needs to be let out just a bit for a looser fit.

There are many ways to ensure you sew the fabric together accurately. My favorite one, especially for beginners, is the magnetic seam guide. When you need to mark and off measurement you I find it useful to mark my own custom seam allowance. Sometimes a pattern will require you to add in the seam allowance. In those instances, you'll want to measure and mark the seam allowance. An adjustable seam gauge is tremendously useful if you need to mark a regular seam allowance around shaped pieces.

For straighter pieces, especially larger ones, I like to use my Dritz Ezy Hem.
