Here's one of the swatches I made. You can see that the linen stitch pulls in much more than the airy lace stitch. For this sample, I used a US size 5 (3.75mm) needle for the lace portion, but a US size 7 (4.5mm) for the linen stitch to achieve a fabric where the body and lace edging "fit" together.
I designed Abbot for variegated, short color run yarns. I love them, but find them very hard to use. I found that I preferred combinations that either highly contrasted or were very similar. To check, I took pictures of the potential combinations in black and white. If the two yarns were black/black, white/black, or white/white -- they were candidates. Similarly, if they were both gray, they were candidates. But white/gray or black/gray were not. In those combinations, the white or black simply overwhelmed the gray and that's all I saw.
Here's what the above swatch looks like in black and white. Pretty much all gray except for those streaks of yellow.
My next sample is even more subdued -- see the color and black and white versions. You can see that the pink will stand out when it's knit up -- but it's mostly gray.
Remember - color is very subjective. There are no color combination police -- the important thing is to find a combination you like.
