Sewing Notes

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 this jacket is slightly cropped, so the hem should hit below the waist, above the hip bone.
  • If you want to adapt the length of your garment to your height, check this helpful tutorial here!

Fabrics

  • When you’re picking out a fabric, go for something that has a little stiffness to it to get that structured look. Steer clear of flowy materials! Also, going for a
    medium-weight fabric is a smart move to keep things from getting too bulky.
  • If you’re using corduroy, be sure to place the pieces so that the pile runs toward the bottom of the garment.

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 use…). 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 you’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.
  • When you’re set to cut the fabric, place it on your work surface right side up, unfolded. Then, lay out the pattern pieces, printed side up, 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

  • Before you start sewing, grab a scrap piece of fabric and try out a few stitches to see how the tension and stitch length look. If the seam isnโ€™t turning out great, try re-threading your machine first. Still not working? Then go ahead and adjust the tension. As for stitch length, thicker fabric usually needs longer stitches, so adjust that as needed. And if your stitches are skipping, switch to a new needle or to a bigger one.
  • If you wish to use topstitch thread, wind the bobbin with a matching regular thread, and be sure to make a tension test on a scrap of fabric before you start to sew. You may need to increase the tension.
  • If you’re unsure how to sew buttonholes, just take a look at your sewing machine manual. The process can differ from one machine to another.
  • For safety reasons, it’s important to pick a thicker sewing needle when you sew with denim. Don’t skip over this step! Check for a 16 or 18 size needle, or one labelled for jeans.
  • You need an unusual tool to sew with denim: a hammer. It will be very handy if you need to flatten a few areas that are too thick. Plus, you also need it to install the jeans button.

Good luck with your sewing project!

    Hi, Zelena: This new jacket pattern looks cute!

    I wonder if you can post a photo of the jacket so we can see how it looks on a model.

    Thanks,

    Marjorie

      Hello!

      I just made this jacket.

      I added an extra 3 inches to the arms and the length since I’m 5’8 and wanted it to go just below my waist.

      It’s a super easy make and very cute.

    I have just cut out this pattern but the front shoulder is too long for the back yolk shoulder. Also the front marking for centre and button hole turning differ top to bottom.

    Am I missing something.

      Are you sure your pattern is printed correctly? The shoulders are matching on all sizes. I’m not sure I understand what you’re saying about the buttonholes. Maybe send me an email with photos.

        hi! I have the same problem for the shoulder yoke, definitely too small..The shoulders donโ€™t match, neither do the shoulder yoke and the back

          It’s impossible, I think your pattern was printed wrong. Check the tutorial on how to print and try the “print as image” tip. You can also send me a photo via email to show me what’s the problem.

      Download the pattern again and print pages 12 and 16 to get the new yoke. Another commenter sent me a photo and I accidentally shrunk that piece when making the pattern layout!!
