I know it can be difficult to find a matching ribbing for the knit fabric you want to use. I have bought cotton and acrylic ribbing in bright colors when I was making sweaters for my kids but I never found a wool ribbing.
If you can’t find the right matching ribbing you can make your own faux ribbing, using the same knit fabric, and a twin needle.
I learned that technique from a Threads magazine article “RIBBING” FOR ANY KNIT FABRIC”
by Dorothy Amo back in 1996 April/May issue 64.
Years ago I made a wool jersey sweater and made the ribbing from the same fabric using a twin needle size 4.0×75
I made the neckband from a folded pin tucked piece of the wool.
After the pintucks were sewn I measured the needed wide and sewed the band together with a regular stitch and finished the outer edge and attached the band around the neckline with a 3 thread serger/overlocker.
I topstitched the band seam allowances around the neckline again with a twin needle.
For the sleeve cuffs I sewed pintucks for a length of 20 cm and finished both edges with a 3 thread serger and traced the part of the sleeves which I wanted in pintucks , sewed the ends together , attached to the sleeves and used 4 cm for the hem wide and hand stitched the hem since I did not want to use a visible line of stitching.
As you can see the sweater is old but it is only to show what is possible if you make the matching ribbing your self.
I made a new sample from a purple knit
I marked the knit fabric on 10 cm and starting to sew pin tucks, the wide between the pin tucks is 4 mm and I have 13 pin tucks for the 10 cm wide fabric which leaves me with 8 cm wide faux ribbing.
The size of the stitch length I used was 2,5 and the tension on high at 8. I used my normal sewing feet and set the needle on 4 towards the right.
I used my sewing foot as a guide for the previous sewn pin tuck.
I used the sample to make a cuff for the sleeve .
The amount of stretch depends on the stretch factor and stretch recovery of the fabric plus the amount of pin tucks. In this case the cuff 10 cm wide and it can stretch towards 14,5 cm.
It is best to make a sample first.
but did not finished the edges as you can see inside the sleeve.
If you want to explore more about this sewing technique try to find a copy of Threads magazine issue 64 which shows detailed pictures and a lot more information.
