For this garment, as it is made out of knit fabric (ribbing) instead of woven, it will be entirely constructed using a 4 thread overlocker instead of a plain sewer sewing machine.
Step One: Lay out the fabric and identify the right side and grainline (which is usually parallel to the selvedge). Place the pattern pieces on the fabric according to the grainline. It is also important to match up the pattern pieces with the patterns on the fabric and to place the pieces all in the same direction of the fabric so it all lines up properly. Make sure to read the cutting instructions on the pattern piece to see if it is cut on the fold, or cut one single so you can place it appropriately.
Step Two: Trace around the pattern pieces with tailor's chalk, and cut out the pieces. For this garment, there will be a pair of fronts (one left and one right), a pair of backs (one left and one right), a pair of sleeve cuffs and a single neckband.
Step Three: To prepare the cuffs, fold one in half vertically with the right sides together and overlock the seam closed. Repeat for the other cuff and the neckband.
Step Four: Place the two front pieces on top of each other with the right sides together and overlock the centre front seam closed so when opened out, the front will be one complete piece with a centre front seam and two different coloured sides.
Step Five: Place the two back pieces on top of each other with the right sides together and overlock the centre front seam closed so when opened out, the back will be one complete piece with a centre front seam and two different coloured sides. Attach the front to the back by overlocking the shoulder seams closed, making sure that the right sides are together once again.
Step Six: Hold the sleeve and the armhole point together with right sides together, and overlock the sleeve into the armhole, holding all the way around so it sits evenly. In a continuous movement, once the armhole is secured, fold the sleeve in half, and begging at the sleeve hem area, overlock the entire sleeve closed. Make sure that the two underarm points match up, and continue on to overlock the garment side seams closed. Repeat these processes for the other sleeve.
Step Seven: To attach the cuffs, fold one in half horizontally so it looks like an actual cuff, put it on the sleeve like a bracelet, so the folded edge points towards the shoulder and the raw edge is connected to the sleeve raw edge. It is important that the cuff seam matches up to the sleeve seam. Make sure the garment and cuffs have right sides out, so it is not on the inside of the turtleneck. Overlock the sleeve cuff closed onto the sleeve, making sure to catch both pieces of cuff and the single sleeve all the way around. Repeat this for the other cuff.
Step Eight: To attach the neckband, fold it in half horizontally so it looks like a properly turtleneck neckband, put it on the neck of the garment like a necklace, so the folded edge points towards the hem and the raw edge is connected to the neck raw edge. It is important that the neckband seam is in the centre back of the garment. Make sure the garment and neckband have right sides out, so it is not on the inside of the turtleneck. Overlock the neckband closed onto the sleeve, making sure to catch both pieces of the neckband and the single neckline all the way around.
Step Nine: To finish the turtleneck, the hem needs to be coverstitched. To do this, either use a coverstitch function on a machine or a specialised coverstitch machine. Fold the hem allowance under to the inside and coverstitch so the underneath will be overlocked and the top side will have two lines of stitching. Give the garment a final and thorough press, making sure all the seams lie flat and smooth to the body.
