Sewing Guidelines

Here are some tips we recommend for a successful sewing project:

Fit and style

  • Choose a size based on your bust. Take a look at the body measurements chart to guide you.
  • To get your bust size, measure around the fullest part of your chest. Take a nice deep breath before you check the number. Just to make sure the measuring tape isnโ€™t too tight. You want it snug, but not squeezing you.
  • On the finished garment measurements chart, see how long the garment is and if itโ€™ll work for your height. Itโ€™s a good idea to compare the length with something similar you already own. Just keep in mind that this top is neither long nor cropped, so it should cover the abdomen, but shouldn’t extend past the hips.
  • If you want to adapt the length of your garment to your height, check this helpful tutorial here!

Fabrics

  • Make sure your knit has the right amount of stretch before you start your project. For this style, youโ€™re looking for about 30% stretch; so if you pull a 10 cm (4โ€ณ) piece, it should stretch to 13 cm (5 1/4โ€ณ) without much effort. If it starts feeling tight before you get there, itโ€™s probably not stretchy enough.
  • Also, pay attention to how the fabric bounces back. If it doesnโ€™t snap back to its original shape after you stretch it, that means it doesnโ€™t have great recovery. This can lead to wavy seams and a stretched-out look by the end of the day. To avoid that, go for a knit that has some spandex (or Lycra) in it. Itโ€™ll help everything keep its shape.

Cutting out

  • Before you start cutting your fabrics, wash and dry them like youโ€™d do for the finished piece. Keep in mind the fabric type and what itโ€™s made of so you choose the right cleaning method (like how hot the water should be or what kind of cycle to useโ€ฆ). Plus, the dyes used on certain fabrics tend to bleed when washed, so wash yours separately, or with similar colors.
  • After you wash and dry the fabric, give it a good press to get rid of any creases. Just make sure your iron is set to the right temperature for the fabric. Generally, synthetic fibers like acrylic, spandex, or polyester should be pressed on low heat, while natural fibers like cotton, wool, or linen can handle higher heat.
  • When youโ€™re set to cut the fabric, just fold it lengthwise right sides together. Make sure the fold is straight and doesnโ€™t twist up. If it does, unfold it and refold until itโ€™s nice and flat. Then, lay out the pattern pieces so the grainline runs parallel to the selvages.
  • Make sure you donโ€™t cut the notches too long; aim for them to be around 0.3-0.4 cm long (1/8โ€ณ). Also, be sure to trace all the pattern markings on the fabrics with a tailorโ€™s chalk or a fabric marker.

Sewing

  • If youโ€™re using a sewing machine to sew with knits, be sure that itโ€™s equipped with a stretch or ballpoint needle. These needles have a rounder tip that prevents snags.
  • If your seams are very wavy, you might want to check for a walking presser foot for your sewing machine. On an overlocker, check to increase the differential or the stitch length.
  • If the seams crack when stretched or pucker, be sure that you used a stretch stitch, and that the thread is all-purpose polyester, not 100% cotton. You may also need reduce the thread tension. On an overlocker, reduce the tension of the needles, not the loopers, and reduce the differential or stitch length.

Good luck with your sewing project!

    Printed this pattern and while putting it together I noticed there was and error. The back piece also say “FRONT”. Please correct this as it will confuse beginner sewists. Otherwise, I think this is another great sewing pattern. I will sew mine up tonight and come back with my review.
