How To Trim A Lining Layer's Hem Length In Dressmaking
When sewing a lined garment, the lining layers are often cut from the same sewing patterns as their corresponding garment pieces. After all, lining is the identical replica of the garment portions it backs, with the exception of one thing: the lining layer should always be shorter than the garment so that when finished, it remains fully hidden and enclosed along the finished hem. If the two lengths were identical, the lining would hang down beneath the hemline and show on the garment's face side.
Sewing Tip: When using the same sewing patterns to cut the corresponding lining pieces, as a first step, trim 1" off the lining's hem allowance width prior to constructing the garment. This will ensure that the lining layer remains hidden on the wrong side of the garment while still offering enough ease to avoid tension and pulling in the finished garment.
