- Place yourself on the reverse of your 2 half-backs
- Straight Half Back: At the slit, fold the 1 cm seam allowance inwards. Iron (again ⚠️ ) to mark the fold
- Fold again by 6 cm: we use the notch to help fold straight. On the top, we therefore have a filled with 1 cm (our seam allowance)
- Iron
- Left Half Back: also fold 1 cm inwards
- Iron to mark the fold
- Fold inwards again by 6 cm: again, use the notch to help fold
- We then come to superimpose our Left Half-Back (2/6) on our Right Half-Back (3/6), aligning the line that we have drawn in pink on the diagram below, and maintaining the folds that we have just marked with the iron:
- We will stitch along the pink dotted lines drawn below: start by pinning all along to hold the 2 Half-Backs together
➡️ Be careful, we don't want to immediately press the slit onto the Right Half-Back (3/6) - the diagram can be confusing. We just want to join the 2 Half-Backs at the slit. We therefore advise you, after pinning, to "fold" your Right Half-Back (3/6) over your Left Half-Back (2/6), right sides together. You get this (piece 3/6 is behind piece 2/6) and you can therefore serenely stitch only these 2 layers together:
- Sew with a straight stitch 1 cm from the edge, remembering, as usual, to backstitch at the beginning and end of your stitching.
- Cut off any excess threads
❓ How to sew a corner? It's very simple: straight stitch all the way to the corner, 1 cm from the edge of the fabric (the value of our seam allowances). Leave the needle in the fabric at this point, raise the presser foot, pivot the fabric and lower the presser foot to continue.
- Overcasting the slit: Position yourself on the zigzag stitch of your machine
- Test your stitch length and thread tension on a piece of fabric and overcast both layers of fabric at the same time.
➡️ Here we use a zigzag stitch that can be made with a family sewing machine, but for those who have an overlocker, don't hesitate to overlock your pieces instead, the result will be even cleaner.
💡 Good to know: if you are working with a fabric thicker than ours, we recommend notching at the corner to open your seam allowance and overcasting each thickness separately:
We will now place the top of our lunge on the Right Half Back:
- Pin the top of your slit to your right half back: make sure everything is flat
- Topstitch 1 cm from the edge, remembering, as usual, to backstitch at the beginning and end of your stitching. In practice, we are going back over the stitching we made earlier.
Congratulations, you've successfully sewn and assembled a slit! You now have a complete Back, which we'll now assemble to the Front.
