Slip Sew-Along #2: Pre-treating Your Fabric
Knit fabrics need to be pre-treated, just like wovens do. Before we start sewing our slips, we'll want to prewash our fabric. This will pre-shrink the fabric, and make it nice and fresh for your first wearing.
The fabric included in the slip kits is called Stretch Micro Jersey, and it's 95% poly, 5% spandex. My preferred way to wash this fabric is to put it on the delicate wash cycle. To dry, either lay flat or tumble dry low. These guidelines should work for other knit fabrics, but use your best judgement and think about how you're going to wash the finished garment. Some people prefer to hand wash lingerie and hang it to dry. If that's your preference, do the same with the fabric to pre-treat it.
One thing I've noticed about the Micro Stretch Jersey is that it can wrinkle while on the bolt, forming a moire-like pattern on the fabric. Washing should remove these wrinkles, but if you still see some, you can remove them by steam ironing the fabric on the poly setting.
Don't worry about pre-washing your trims and elastics. They won't shrink, and they'll probably just get all tangled up in the wash!
Next week we'll start cutting and sewing!
