Chaning the Bicep on a Sewing Pattern

Biceps are an important part of the sleeve pattern, as they can greatly affect the fit and overall look of a garment. Whether you are making a shirt, jacket, or dress with sleeves, it is essential to ensure that the bicep area fits well and is proportional to the rest of the garment.

If you find that the bicep area of your sleeve pattern is too tight or too loose, you may need to make some adjustments to the size. Fortunately, this is a relatively simple process that can be done with just a few measurements and some basic math.

To begin, take your sleeve pattern and measure the circumference of the bicep area. You can do this by wrapping a measuring tape around the widest part of the sleeve, just below the sleeve cap. Write down this measurement, as it will be used to determine how much you need to adjust the pattern.

If the bicep area is too tight, you will need to add some extra room to the pattern. To do this, first determine how much additional space you need by measuring the circumference of your own bicep and subtracting the circumference of the sleeve pattern. For example, if your bicep measures 33cm and the sleeve pattern measures 31cm you will need to add 2 cm to the pattern.

If the bicep area is too loose, the process is similar but in reverse. You will need to subtract the difference between your bicep measurement and the sleeve pattern measurement, and then divide that number by two. This will give you the amount of space that you need to remove from each side of the sleeve.

Making adjustments to the bicep area of a sleeve pattern can seem intimidating at first, but with a little practice, it becomes easier. By taking accurate measurements and carefully redrawing the pattern, you can ensure that the sleeves of your garments fit comfortably and look great.
