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 that the hem should reach the hips.
  • If you need to adapt the length of your garment to your height, check this helpful tutorial here!

Fabrics

  • This pattern is suitable for sweater knit, a fabric made to look like it was hand-knitted and is available in various thickness and textures.
  • Make sure your knit has the right amount of stretch before you start your project. For this style, you’re looking for about 50% stretch; so if you pull a 10 cm (4โ€ณ) piece, it should stretch to 15 cm (6โ€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 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.
  • 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). You should also notch the pieces cut on the fold to mark the center front and back. To do so, cut right in the fold line.

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.

Sewing instructions

Just a quick reminder that, unless stated otherwise, your seam allowances should be 1 cm (3/8โ€ณ) wide. Also, be sure to sew with a stretch stitch, like a zigzag, or a 4-thread overlocker. If youโ€™re using the overlocker, place the left-needle mark 1 cm (3/8โ€ณ) away from the fabric edge and the blade will cut away any excess fabric.

  1. SHOULDERS: With right sides together, sew the front and back panels at the shoulders. Press the seams to the back.
  2. COLLAR: Fold the collar in half, right sides together, and sew the center back seam. Be sure to match the double notch as you go, then press the seam to one side. With wrong sides together, fold the collar onto itself and align the remaining raw edges.
  3. With right sides together, sew the raw edges of the collar to the neckline, matching the seam on the collar with the center back. Be sure to stretch the collar as you sew and align the shoulder and center front notches. Lift the collar and press it so it lays flat.
  4. SLEEVES: With right sides together, sew the cap of the sleeves to the armholes. Be sure to align the corresponding notches as you sew. Then, press the seams toward the body.
  5. SIDE SEAMS: Place the front and back of the garment with right sides together, folding the sleeves lengthwise. Then, sew the side and underarm seams, aligning the armhole seams as you go. Press the seams to the back and turn the garment right side out.
  6. BELT: Fold the belt in half, right sides together, and sew the center back seam. Be sure to match the double notch as you go, then press the seam to one side. With wrong sides together, fold the belt onto itself and align the remaining raw edges.
  7. With right sides together, sew the raw edges of the belt to the bottom of the garment, matching the seam on the belt with the center back. Be sure to stretch the belt as you sew and align the side and center front notches. Fold the belt down and press it so it lays flat.
  8. CUFFS: Fold the cuffs in half, right sides together, and sew the short sides. Then, press each end of the seams in opposites directions to prevent bulk. With wrong sides together, fold the cuffs onto themselves and align the remaining raw edges.
  9. With right sides together, sew the raw edges of the cuffs to the bottom of the sleeves, matching the seam on the cuffs with the underarm seams. Be sure to stretch the cuffs as you sew and align the corresponding notches. Fold the cuffs down and press them so they lay flat.

Good luck with your sewing project!

    Hi,
    I have been using your patterns for a while now and love them. Lately, your website has been cluttered with ads making it difficult to view content. I know you need these to make a living but is there a way to cut back on them or something ?

    Thank you for the free pattern. I’ve just downloaded the #UP1074. Although it’s not size inclusive, I can still make this work. Would love to see more size inclusive patterns…but these are free so not really a big deal…but would like to see more sizes available.
