What about the House stripe pattern for wizard school knitwear?
The stripe sequence of "House" colors is added to specific places, depending on the style of sweater you are knitting:
This holds true whether you are knitting the vest, the school sweater or the cardigan. It is our opinion, with the benefit of experience, that adding stripes or any fair-isle design, a couple rows above the ribbing prevents the ribbed stitches from distorting the edge of the design.
The stitch distortion is particularly noticeable when knitting the stripe pattern with worsted weight yarns.
Again, this is OUR opinion but the idea here is to reproduce the "look" of the Hogwarts© school uniform knits, which includes the proportion of the stripe as a pattern over the entire sweater.
We will leave the ultimate placement, and size, of this stripe pattern up to the individual knitter as there are numerous and differing opinions as to the "authentic" placement of the stripe.
The sample on the immediate left, knit in Patons® Classic Merino Wool, illustrates a 2/2/2 "COS style" stripe sequence. At this stitch and row gauge, the House stripe pattern is .94 inches wide.
The width of the full stripe may be "in proportion" for an adult sized sweater but too wide, and seemingly out of proportion on a child's pullover.
When knitting a child's sweater, you may want to reduce the width of the stripe by knitting in a 1/1/1 row sequence.
Displayed below are three stripe patterns knit in various fibers.
They illustrate the difference in the width of the stripe pattern when using different fibers.
On the left, is a "PoA" stripe knit with KnitPicks© Merino Wool. In order to achieve the narrow/wide/narrow look of th PoA stripe, and maintain a good proportion, we had to reduce the stripe pattern to a total of four rows.
The blue and silver, trapped bar stripe pattern pictured in the middle was knit in Patons© Classic Merino Wool. In this rib knit sample, a 4 row stripe was nearly one inch wide.
However, when knit in stockinet stitch, using the same Merino Wool, the classic Chamber of Secrets® styled House stripe pattern should not be more than four rows wide in order to maintain proportion in an adult sized sweater.
