Sewing Notes

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

Fit and style

• Choose a size with your bust. Refer to the body measurements chart.
• On the finished garment measurements chart, you can also check the length of the garment and see if it’s suitable for your height. You may want to compare the length with a similar piece of clothing. This jacket is long and should fall slightly below the hips.
• If you want to adapt the length of your garment to your height, check this helpful tutorial here!

Fabrics

• Choose from a wide range of fabrics; lightweight options to stay cool in spring and summer, or heavier ones for warmth in colder weather. If you choose a heavier fabric, make sure to switch to a sturdier needle.
• If you’re using a plaid flannel, you may need more fabric than indicated for pattern matching.
• 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 you’d do for the finished piece. Keep in mind the fabric type and what it’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 doesn’t twist up. If it does, unfold it and refold until it’s nice and flat. Then, lay out the pattern pieces so the grainline runs parallel to the selvages.
• Make sure you don’t cut the notches too long; aim for them to be around 0.3-0.4 cm long (1/8″). Also, be sure to also trace all the pattern markings on the fabrics with a tailor’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 isn’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’re unsure how to sew buttonholes, just take a look at your sewing machine manual. The process can differ from one machine to another.

Good luck with your sewing project!
