For my Seneca Garment Construction class, I had to make a lined skirt with slant pockets and a vent. I chose a pattern that had neither.
Still, I liked the shape well enough and decided to make the changes. A slant pocket is not so hard to add. It requires cutting the desired shape on the front pattern piece, adding seam allowance and creating a pocket bag. I was able to do this quite easily.
I maintained a copy of the original front pattern, to be used as the lining.
That was the easy alteration. The vent was a little trickier. The back pattern remains the same for both back pieces and one (right) lining piece. I made the vent two inches wide.
This piece is then used to trace the opposite (left) lining piece. They fit together like a jigsaw puzzle.
For the actual construction, the marking were quite meaningless. The key is to not sew off the end of the vent, which is what I typically do when sewing regular seams. The seam must end at the point. The lining pieces will not match until later, when they are forced to do so.
I learned a lot doing this skirt. I think it turned out really well and I am pleased with my work. I had a few issues in getting there (see The 42,5 hour skirt), but I like what I ended up with.
My finishing was done well. I hand stitched the lining to the zipper tape. I really prefer this method to machine sewing, as so many fabrics, particularly lining fabrics, like to shift under the presser foot.
I am getting better and quicker at lining a vent. In this project alone, I started at about 4 hours and am down to two. I’m very fussy!
My final mark was 18/20. One of my front darts was longer than the other and I had a small pucker at the waistband.
