I’ve been waiting for the perfect yarn to knit a guinea pig sweater or two for a long time and I finally found it. Well, more like it found me!

Bis-sock yarn in the color Bouquet, hand-dyed by Biscotte Yarns.

Bis-sock yarn in the colorway Bouquet, hand-dyed by Biscotte Yarns.

Quebec-based, Biscotte Yarns specializes in hand-dyed yarns, particularly in self-striping colorways (as you can see above and on their web site) – the colors are très magnifique! I was lucky enough to be given a skein to play with and as soon as I saw it and touched it, I knew it would become a guinea pig sweater.

Each skein of Bis-sock yarn is 100 gr (3.5 oz) 400 meters (435 yards) and is made of 85% merino superwash and 15% nylon. That combination makes for an extremely soft yarn (only the best for the guinea pigs), and one that’s machine washable.

Sticky the Guinea Pig

The pattern I’m using to knit the sweater is a modified (corrected) version of a free pattern called Nicholas’ Guinea Pig Sweater by Knitter’s Row – here it is with edits:


  • 200 yards of Bis-sock yarn self-striping hand-dyed yarn (one skein is 435 yards, so you should get two sweaters if you have two guinea pigs like I do), I’m using the colorway Bouquet
  • Size 3 knitting needles (I’m using double-pointed, original pattern calls for circulars)

Many people have commented that this pattern contains a few errors, I’m pretty sure I fixed most of them. I knit the first part flat using dpns, and then in the round once the front and back were done. When you repeat rows 2 and 3 to 1.5 inches (in the front and back sections), that length represents the size of the arm holes.


Cast on 88 sts.
k2, p2, rib for 2 in.
Separate sts. for front (40 sts.) and back (48 sts.).

Row 1: k2, p2 – inc. every 3rd st. (kfb)
(64 sts. total)
Row 2: p6, k2 (wrong side) to end of row.
Row 3: (right side) p2, k6 to end of row.
Repeat rows 2 and 3 for 1.5 in.
Place sts. on waste yarn

Pick up other 40 sts.
Row 1: k2, p2 – inc. every 5th st. (kfb)
(48 sts. total)
Row 2: p6, k2 (wrong side) to end of row.
Row 3: (right side) p2, k6 to end of row.
Repeat rows 2 and 3 for 1.5 in.
Place sts. on waste yarn

Pick up back stitches and knit in round k6, p2 for 5 in.
Bind off all sts.
Weave in ends and turn down neck.

Note: I found the increase rows very confusing. The way I got through it was to talk it through. Miraculously, it worked.

Here is my own progress below, I’ll post more pictures here every day until it’s finished:


So far the yarn is excellent to work with and I just love how the striping is turning out.

    Hi Danielle, thanks so much for this pattern. My daughter has two guinea pigs and I told her I would make some sweaters for them. Not until I started searching did I realize that there were only a couple that I could find. Some blogs are nowhere to be found now. Not sure what happened to them. I am quite new to knitting but eager to learn. I am using a circular needle since I don’t have dpn. Do i read the pattern the same way? And when you said Front and Back, do I use another needle to finish the front and back and then knit in round? I just finished the 2″ rib.

        Danielle, sorry to bother you again. When I was working separately for the front and back, I assumed I needed a 3rd needle, correct? Since I did that, my circular needle is all twisted now. Am I doing it right? I don’t see a way to work in round🙁

          Moving this to email, thanks.
