- Place one of the 2 Tops on one of the 2 Sides, right sides together
⚠️ Be careful not to get the direction wrong: we will of course assemble the Top to the less flared part of the Side, and not the other way around:

➡️ The diagram below helps you understand what we are trying to do, so we have shown you the bob on the right side, but since we are assembling "right side against right side", it is easier for you to turn your pieces inside out to pin everything properly.
To pin the two together, use the notches at the 4 cardinal points on the top:
- a first notch is placed right on the stitch that we have just made on the side
- the opposite notch is placed at the level of the fold on our side (when we cut it "at the fold")
- the last 2 notches must coincide with the middles of these 2 half-sides
➡️ It may seem complicated said like that, but see below what it looks like, with a top view, it's immediately clearer:

- Pin the entire circumference of the bob. Don't hesitate to use a lot of pins to ensure precision.
➡️ Are you finding it difficult to make these two pieces fit together edge to edge? Do you feel like the edges aren't exactly the same length at all? Don't panic, this is perfectly normal. It's due to what's called "gap."
❓ What is fullness? Fullness is an excess of fabric that needs to be absorbed from one piece in order to assemble it with another. We have fullness every time we try to assemble two curved lines that don't have the same trajectory. We also often plan for fullness during pattern making in places where we need ease: this is often the case, for example, at the armholes. This is what will make your garment comfortable and, above all, it's what will allow you to move in it! Properly "distributing the fullness" actually means distributing the small "holes" formed by our fabrics evenly, in order to avoid creating creases. If you've never heard of fullness before, we recommend you refer to our tutorial video to see how to properly distribute the fullness on your < villette > bob.
⚠️ Be careful to pin the side seam allowances well too: we ironed them open earlier, so pin them open as well. It may seem like a detail, but respecting the direction of the seam allowances allows you to avoid unsightly excess material. Generally speaking, we iron the seam allowances when we want to distribute the material evenly.
💡 Tip: For those who prefer, you can also "baste" your bobby pin (and therefore pre-sew by hand with a loose stitch) instead of using pins. Basting is often used in sewing when joining two pieces seems tricky.
- Still using a straight stitch, sew 1 cm from the edge, making sure to secure your stitch at the beginning and end. Take your time and again, be careful when sewing your seam allowances (which you want to keep open). Trim any excess threads.
➡️ This step is certainly the most tedious of our project because the rounding makes the task complicated. Be patient, breathe, and everything will go well!
- Notch the seam allowances to obtain a nice rounded shape on the top of your bob.
❓ How to notch a curve? It is important to notch the curves when sewing: this allows the fabric to position itself neatly, without pulling or warping. As we did to mark the notches when cutting our different pieces earlier, take your fabric scissors and make small cuts (0.5 cm, no more) evenly on the seam allowances, going all the way around your hat (every 2 or 3 cm). Again, be careful not to cut too close to the stitching, or you risk making a hole.
- Iron everything, placing the seam allowances down (against the side). You will have the first bottom of the bob.
- Do the same with your 2nd Top and your 2nd Side in order to obtain a second Background of bob
