Knit chiffon, or tissue knit: absolutely a gorgeous material to work with. Typically made in 100% cotton and often with a slightly slubbed appearance, this luxe fabric usually has stretch with little if any recovery. I find making a size down, the garment will often stretch with time. In order to shrink it back, you will have to occasionally put the garment in the dryer (remember those tissue tees so popular with the GAP etc, in the late nineties?).
Sheer and semi-sheer fabrics are absolutely wonderful, in that each seamline, dart, and detail is really shown off – like a stained glass window. I tend to make french seams in these garments. And for a bit more interest, here I demonstrate how to create simple 3/16″ pintucks in a black knit chiffon.
1. prewashed and dried fabric
2. marking chalk
3. cutting mat, rotary cutter, and see-through cutting ruler
4. masking tape
The first thing to note about tissue knits is the grain can often be quite distorted – in other words, not parallel to the selvege. When laying out your yardage you have to determine if you need to cut the pieces on the grainline or no. For the front panel of this tunic, I decided to cut off the grain since I’d be making two rectangular panels abutted together, and could flip the grain (to chevron), making the garment symmetrical. For the sleeves, neckband, sleeve band, and back panel, I cut along the grain in one layer.
Shown below; the yardage arranged with the grain corresponding to the cutting mat; you can see what I mean about the selvege.
Now for marking tucks, it is best to cut the fabric and leave it be on the mat – don’t shift it whatsoever – then mark right away. Cut out your panel according to your cutting mat; next you’ll be marking the centerline of your tucks.
When marking, I use a ruler and line it up with the guide lines on the mat; the sheer nature of the fabric makes this easy to do! You want to be very careful and apply firm vertical pressure to your ruler as you mark, or else you will shift your fabric. If you do shift it, just carefully rearrange to the guidelines on the mat.
Here I am applying lines at a 45 degree angle.
Be patient; this is the most exacting part of the process. It’s easy from here on out!
Once you have your tuck lines marked, take the piece to the machine.
Using a straight stitch or a very narrow zig zag, start your stitching line on your first tuck, folding right on the chalked line and making sure you are stitching at the width you want. My tucks are 3/16″. After you’ve started your tuck successfully, pause and retrieve your roll of masking tape.
I like to create a little seam guide by layering about six layers of the masking tape very accurately on top of one another, then applying it to my machine bed. This will help you get exact tucks – note you can use this method to create tucks as deep or shallow as you like!
Make sure not to stretch your fabric as you stitch. Just let the machine action guide the fabric through.
Below, I am about 60% of the way through my tucks. They may look a little wavy but don’t fear – we will be pressing them and they will be #legit!
The pressing is the most fun. Taking them to your pressing surface, carefully press each tuck as-sewn and then, if you like, you can press them a particular direction.
These tucks can be used to create interest in any project – gowns, tops, robes – what-have-you. They add a bit of drama and set your garment apart from others!
