To neatly and professionally finish the seams on the chiffon for my designed garments I have sampled three different styles of seam finishes; French seam, clean seam and overlocking.
French seam is where the wrong sides of the fabric are sewn together before being pressed,the excess is cut close to the line of stitching, a few mm away and folded so the rights sides of the fabric are facing. Then another line of stitching is needed to conceal the raw edge of the fabric.
This style of seam is the most professional in appearance and appropriate for the lightness of the fabric.
However this style is slightly time consuming because it effectively means seams must be sewn twice and this method can only be used of straight seams.
The second method of seam construction I sampled was the clean finished edge. In this techniques the seam is sewn, ironed opened before the seam edges are turn under and sewn flat.
The raw edges of seam are concealed as desired however the seam is not as strong when compared to the french seam.
This technique of seam finish would be more suited to a medium heavy weight fabric rather than the light weight chiffon.
Out of the three seams finished this technique took the longest due to three lines of stitching need to finish the seam.
The last sample seam was an overlocked seam.
After stitching the seam the edges are overlocked, cutting the seam down and preventing fraying in the finished seam.
This is probably the most commonly used way of finishing seams due to quickness of finishing seams. Overlocking seams also strengthen the seam, making the garments more stable.
Yet this seam does not have professional finish desired and with the sheerness fabric can be seen though the fabric.
I believe the best seam to use on my garments would be the french seam because of the strength in the seam, aesthetically pleasing finish and is approbate for the fabric.
