Lace fabrics are of an open work design which comes in various weights and patterns, any fibre can be used but most common are polyesyter, nylon, viscose and cotton. Stretch lace should be treated as a single knit. Use for very simple designs with minimum seams to showcase the fabric, overlay the lace on various coloured plain backgrounds you will be surprised how different the lace can look on different colours, if you lay coloured lace on a self coloured background you can lose the impact of the lace design.
Sew with a 70/10 or 75/11 needle, depends on the weight of the lace use atiny,short zigzag, 0.5mm width, 1.5mm length but do play on scraps of fabric to see which stitch length/width looks/works best on your weight of lace.Tip.....stabiliseshoulders and waistlines with stay tape (the selvedge of silk organza is perfect for this...but does make the garment dry clean) Tulle gives body and keeps the lace transparent, silk organza can be used as an underlining also. Flesh toned stretch lining works best with stretch lace.
When cutting out placement is extremly important, think where the prominent motif will be positioned when the garment is made. Tip...lace can be joined invisibly by overlapping the pieces, matching the outline design as closely as possible, oversew by hand or by machine zigzag . The surplus lace can be trimmed away leaving a single layer. To press use a fluffy towel so you do not flatten the motifs.
Most laces are washable but do take care, by hand might be the best method, if silk organza has been used in construction the garment will be dry clean only.
