BIOSOCK – Yarn with Biodegradable Nylon!

  • Skeins of bright fluorescent hand-dyed yarn.

This month’s update at Undercover Otter features our new yarn base: BIOSOCK.

I’ll be honest, I’ve heavily fallen for this yarn base. It’s soft as butter, works up quickly in projects and takes dye vividly. This smooth 4-threaded fingering weight yarn is a perfect mashup between the softness of Merino wool and the longevity of nylon, with a biodegradable twist. It knits up perfectly for garments and other next-to-skin soft items.

BIOSOCK is our first yarn base that uses biodegradable nylon. This yarn will last as long as any other nylon blend since the nylon will only degrade when it reaches the garbage processing facility. There, special enzymes and micro-organisms are added to the waste, which break down the biodegradable nylon in the course of three years instead of the 40 years it takes most man-made fibers to be broken down.

The deets:
Fiber contents: 75% Superwash Merino / 25% Biodegradable Nylon
Weight per skein: 100 grams / 3,5 oz
Running Length: 400 meters / 437 yards
Yarn Type: Fingering / Sock
Threads: 4-ply spun

With a yarn base called BIOSOCK, you probably already guessed that we got our inspiration for this month’s update from the Bioshock games. I (Aiden) love these dystopian games, even though some of them are getting eerily close to current day events.

We dyed up a bunch of semisolids in especially our Neon and UV reactive range, as well as a bunch of amazing colorful speckles that were first featured in our Pride Collection earlier this year. You can also find a range of three-skein sets on our website, which are perfect as a springboard for your creativity.

Last but not least, we’ve updated our sale section, so have a browse and snag up a bargain!

Undercover Otter’s Halloween Colorway is here!

  • An illustration of an otter and the words Halloween is taking shape.

It’s that time of the year again. The most spooky of seasons is rapidly closing in on us, like a slasher to their last victim.

This year we’re offering an exclusive colorway dyed on our Squirm Sock yarn base.
As inspiration we’re using the original Halloween movies, and its many sequels, re-imaginings, reboots and other incarnations, especially the 2018 continuation of the original Halloween, in which Laurie Strode has to face off with Michael again after him being incarcerated for 40 years.

You can see a sneak peek at the colors we’re being inspired by in the second image. Yes, there will be neons, no it will not be a semisolid, that’s all we’re saying for now though. 😉

We offer 2 options to choose from:

Option 1 – Yarn & Swag Bag, which contains:
– 1 Skein of Squirm Sock in the Halloween 2021 surprise colorway;
– 1 Neon is my Neutral Tote Bag;
– 1 Neon is my Neutral Notions Pouch;
– 1 Set of 4 Slasher Otter Stickers;
– 1 Set of 4 Neon is my Neutral sew-in tags;
– 2 Undercover Otter Enamel Pins (Slasher Otter & Your Mother Darns Socks in Hell);
– 1 Your Mother Darns Socks in Hell Iron-on Patch;
– 1 Mask to bring out your inner beauty.

Option 2 – Yarn Only, which contains:
– 1 Skein of Squirm Sock in the Halloween 2021 surprise colorway;
– 1 Set of 4 Slasher Otter Stickers;
– 1 Mask to bring out your inner beauty.

Items are ready to ship on September 30th.
If your order contains items next to the 2021 Halloween Special, they will all ship at the same time.

The Clan of Igors, an Undercover Otter Cinematic Yarn Club

Join Undercover Otter on an adventure in 2019 in which we highlight the life and growth of The Igor in show business through offbeat and colorful hand-dyed yarns!

In 2019, we’re stepping up our yarn club game by turning it into a monthly festival of yarn with the bonus of interesting facts in what we like to call our “Ghoul School.”

When you think of Frankenstein as a collective mythology, there are a few specific things that come to mind. Naturally there’s the mad doctor, a gloomy laboratory and a creature cobbled together from random body parts. But one trope that seems unparalleled in its ubiquity is the presence of an “Igor,” a slightly awkward assistant to their “Master.” You may be surprised to hear that no such character ever appeared in Mary Shelley’s original book. But with all the adaptations that her book has gone through, Igor “stuck” after he came into existence and is now synonymous with the henchman of the mad and power hungry.

Why, though, has Igor stayed with us as a concept? Why have often hunchbacked, assistants become so entangled with the Frankenstein stories? In 2019 we are going to take you on a journey to discover how the Igor archetype developed and which movies played an integral part in the ongoing legacy of our favorite helping hand (attachment of said hand optional).

In this cinematic yarn club, we will be diving into the first onscreen Igor, the first female Igor, an Igor-flavored horror host, a comedic Igor, singing Igors, unconventional Igors and modern Igors.

Being part of the Clan of Igors means an exclusive Igor colorway shows up to your doorstep, ready to aid you in your fiber crafts. To best cater to our sock, shawl and garment knitting members, the Clan of Igors colorways are available on five different bases: Squirm, Strain, Mighty Merino, Singularity and Mighty Merino DK.

Colorways are revealed publicly at the end of the month. Colorways made in this monthly club are exclusive to the members of the Clan of Igors for six months. After this, we might add them to our colorway portfolio. Some of our source material may be in black and white, but trust us, the skeins we send out will not be monochrome. You know us by now — neon is our neutral.

What’s included every month?
– Your Clan of Igors shipment contains a unique colorway, hand dyed by Undercover Otter in the yarn base of your choice.
– Depending on which of the two subscriptions you pick, you will receive one or two skeins; in the case of the two-skein subscription, both skeins will be dyed in that month’s colorway.
– Also included is information on how that month’s Igor relates to cinema and why we love them so much.
– Any and all extras included differ per month.

The List of Movies we will be exploring:
January: Frankenstein (1931)
February: Dracula (1931)
March: Son of Frankenstein (1939)
April: House of Dracula (1945)
May: Horror hosts of the late 60s
June: Manos: The Hands of Fate (1966)
July: Monster Party (1969)
August: Young Frankenstein (1974)
September: The Rocky Horror Picture Show (1975)
October: Frankenhooker (1990)
November: Victor Frankenstein (2015)
December: The Nightmare Before Christmas (1993)

Undercover Otter Pre-Orders Open

In the past year we’ve noticed that some of our colorways run out faster than others, which means we had to disappoint quite some people that are looking for that sweater quantity of Scumbot from one dyebath, or a specific combination for the latest Fade fad. To remedy this (and keep our sanity intact) we’ve decided to open up preorders while we’re looking for a bigger studio (so we can get back to regular updates).

Pick your poison and combine our palette of 40+ repeatable colorways with three different fingering weight bases: Squirm Sock, Mighty Merino and Singularity.

Preorders are open right now and run till January 28th 2018. All preorders will be dyed, dried and dispatched in week 4 and 5 (22 January – 5 February).
