Color Fun with Color Grown Cotton


I did an experiment! Above are two swatches. The one with the tag is what I ship when someone places an order. The other one is smaller, unlabeled, and has a black Sharpie dot in the corner. The one with a black dot was soaked in cold water as part of my experiment. I'll get to that in a moment.

One of the most fun things about color grown cotton is its ability to deepen in color when washed in warm, alkaline water. As it says in my fabric description:
Since the yarns are not dyed, the colors do not fade in the wash. The colors actually become deeper with each warm water washing, especially in alkaline water, until they reach their full potential.
The absence of dye may make the fabric good for babies and others with sensitive skin. The color deepening effect is a fun property for anyone to play with. Though I've observed subtle color deepening when I first began knitting the yarn and washing the swatches in warm water, I hadn't done a controlled experiment until now.

The fabric is washed in cold water and tumble dried at the knitting mill as part of the production process. Cold water does not seem to have an effect on color. Tumbling in a hot dryer doesn't seem to have an effect either.

For my experiment I worked Mesa Plaid fabric, the solid color grown light green ribbing, and color grown tan ribbing. Each swatch was cut into two pieces. The pieces with the single black dots received a cold tap water soak for 15 minutes and were allowed to air dry. The pieces with two dots were soaked in a bath of 2 teaspoons of baking soda dissolved in 5 cups warm (comfortable for my hands) water for 15 minutes and also air dried. Here are the results.
Hoping to get consistent lighting as my experiment continues, I've used artificial lighting for this photo. The deepening of the color is more apparent in the light green yarns. The deepening is present in the tan too, though I'm not sure the difference is captured in the photo. I don't know what the "full potential" shades of the fabrics are, but I'll continue to soak the three bottom swatches from time to time to see what happens.

Determining the Length and Width of Rib Bands


Because the designer of a sewing pattern can only suggest fabrics and ultimately won't know the elasticity or recovery of the fabric you've chosen for your garment, I think it's often best to draft your own rib bands. This is especially true for the neckline, where having a band that lies flat in a round or scooped neckline shape can be challenging. The best part of drafting bands is that they're easy; they're rectangles.

Step 1.  Choose fabric that's suitable for your project.
I think it's best to chose a relatively lightweight ribbed fabric with this method, because in its finished state, the ribbing will be double the original thickness. My preference is to use a soft and very stretchy rib. The fabric doesn't even have to be a rib. A jersey that's stretchy and has a good weight when doubled will also work. Good recovery is helpful, if you want a snug band. If the fabric doesn't have good recovery, try inserting a layer of thin power mesh between the layers. Frankly, however, I prefer my bands on the loose side and never use mesh. It all depends on the look you're after.

Step 2.  Determine the width needed.
If you'd like a neckband with the finished width of an inch, the width of the rib fabric you cut will need to be 3 inches altogether. That's 0.5 inch seam allowance, one inch for the public layer of the rib, one inch for the inside layer, and another 0.5 inch seam allowance. (Substitute your own figures.) Also, know that if you need to stretch the ribbing a whole lot in the next step (Step 3), the width of the band will be slightly narrower than the one inch you were aiming for. Draft the band a little wider, if this is an issue.

Step 3.  Determine the length needed.
The length will really depend on the look desired and the stretch and recovery factors. You might want the cuffs at the wrist to really gather the bottom of a relatively wide sleeve, or perhaps you don't want any gathers at the hips. I used to always make the neckband three-fourths the circumference of the neck opening. But since all ribbing is not the same, sometimes adjustments had to be made. Unsewing happened.

There's a better way to determine the length. First, measure the neckline with a tape measure. Now lay the tape measure flat on a table and stretch the folded ribbing until it reaches the length measured for the neckline.

For example, if the neckline measures 25 inches, perhaps it will take a 20-inch length of ribbing to stretch the full 25 inches. Be sure to make it a comfortable stretch with no strain. Add an extra rib or two on each end for a seam allowance and you now have the perfect length for your band.

Step 4. Consider the band seam too!
If your sewing pattern gives you instructions for inserting the band in the round (my favorite way), the next step is usually to sew the short ends, the neckband seam, so that the band becomes a circle. I prefer to sew through the knit stitches (the ridges of the ribbing). That way, when the band is folded, the seam falls on the purl stitches (the valleys of the ribbing) and isn't very visible. Sometimes I even go so far as to baste this seam first to get it just right. After basting is also a good time to check that the band actually fits over your head (or hand or hips).

Even before steaming, the seam is almost invisible while the band is relaxed.
After the folded neckband is sewn to the garment, steamed, and allowed to dry, the band will stretch nicely where it connects to the garment, yet lie flat against the body.
