|Several people have asked me to add these tips to this file. This applies to lightweight jerseys like rayon or matte jersey that have alot of drape.
*Pre-wash all jerseys....many will shrink, especially rayon, silk and cotton.
*Use 1/2" bias strips of lightweight fusible knit interfacing (Dream Weave, Touch of Gold II, Sewers Dream, etc.) to reinforce any horizontal or bias seams, such as necklines, shoulders, and armscye. Match the length of the strips to the pattern piece, not the cut fabric, and then fit the fabric to the piece before fusing. I do not usually reinforce vertical seams unless the fabric has alot of lengthwise stretch.
*Use either a very narrow zigzag (.5 wide and 2.0 or 2.5 long)or stretch stitch for your seams (or use a 4-thread serger overlock).
*Use a walking foot attachment or make sure your push your fabric toward the foot/needle as you feed the fabric in to avoid stretching seams too much. I love my Pfaff because it some with the walking foot built in.
*Fully interface all your hems with strips of fusible knit interfacing the width of the hem before turning the hem up and stitching in place. I even do this if I use my serger coverstitch to finish the hem, because it helps the garment hang so much better. I use same type of interfacing as noted above but not cut on bias.
*If you finish your raw seam edges with an overlock stitch, make sure that you use a fairly long stitch to avoid having too much bulk, especially if you serge the seam edges together. This bulky serged edge can create bumps/waves that show on the outside, especially when you press the fabric.
*Use steam more than pressure from the iron to press open seams and to finish your garment. Rayons and silks are very prone to getting iron marks and shiny areas from the iron, even on low temps. I try to steam while holding the seam up off the ironing board or while the garment is hanging. Pressing over a velvaboard or piece of thick velvet or terrycloth helps too.
*Let rayon and silk jerseys hang for a day or two before hemming....they stretch some in length.
