Neck and armbands can be tricky. They really just require practice. Measurements (as I always put in my tutorial) should be used as a guideline and not precise for every garment you sew. Why??? EVERY knit fabric is different. So depending on the fabric you use you may need to adjust the measurement given in a pattern. The video below I show several different knits- even the same KIND of knit (cotton lycra) can be completely different from one brand to another. Watch the video below to learn how to decide if you need to alter your band measurement, it will save you a lot of headache! Band measurements are usually written for 85% the opening (neck or arm, etc) and for something like ribbing that is VERY stretchy and has great recovery. If you aren’t using the suggested fabric (ribbing) with 75% stretch you will need to alter the measurement.
How do you know how much stretch your fabric has?? If you cut a 4″ x 4″ square of fabric, then fold in half (just like you would a band) hold one end and see how far it stretches.
If it stretches to 8″ it has 100% stretch
7″- 75% stretch
6″ -50% stretch
5.5″- about 40% stretch
5.25″- about 30% stretch
5″- about 25% stretch
Sewing your bands in the round or flat? You quarter your bands and bodice but you still have trouble? This video below shows different techniques and demonstrates how to use them.
