Yarn Bases

Here you will find a list and description of our many yarn bases.  You can order most of our colours on any of these bases.  Not all colours can be dyed on every base, but we do our best!  If you can't find the colour/base combination you are after, please feel free to contact us.  
All of our bases are available to purchase undyed - you can shop them here. 
Our yarn is ethically produced, which means no creature died for it to be created, or was mulesed for human convenience.
It is recommended that all Obsession Yarns bases be handwashed in a tepid (room temp) bath with a no-rinse woolwash, and then dried flat out of direct sunlight to preserve colour and quality.
Our bases are arranged with an alphabetical order which makes it easier for you to remember your favorite!  Click on the links in the list below to learn more about each base.

Our personal favorite at Obsession Yarns - this sublime yarn is basically a cloud in the form of 4ply yarn.  It slides through your fingers like the softest thing ever, and creates magical pieces of art!  More suitable for beautiful, intricate shawls or lightweight tops, cardigans or pullovers.  Definitely the choice for a special piece made to last or be given as a special gift.

Base G - 5ply Pure Merino

Base H - 8ply Pure BFL
100% Bluefaced Leicester

BFL has a little more tooth - meaning it's slightly more rustic feeling and a little less soft than merino.  Don't be fooled though!  BFL has a beautiful, natural sheen and it softens with wear.  It is truly a beautiful fibre to work with and we highly recommend trying it!  BFL makes the best hats, beanies and sweaters!

Base H - 8ply Pure BFL

Base I - 8ply Sparkle
60% Merino/10% Alpaca/26% Nylon/4% Metallic

One of our bases that have been with us since the beginning, this gorgeous sparkly dream is a favorite!  The blend is so beautiful, with just a hint of alpaca for extra added softness.  It is accented with a touch of nylon allowing the creation of sparkly socks, because we all need those amiright?  This yarn transforms as you create magic with it, and the metallic thread turns into a subtle glimmer.  A must try!

Base I -  8ply Sparkle

Base J - 8ply Merino/Nylon
85% Merino/15% Nylon

This lovely 8ply merino with added nylon for strength has a beautiful bounce and loft, and is the perfect staple for your thicker socks and garments.  It is great for accessories and colourwork too!

This gorgeous singles base is a roving style - but has excellent strength.  It is perfect for fast beanies, scarves, cowls, shawls or mitts.  She might pill a little for sweaters, but with some maintenance it would still be amazing!

Base N - Chunky Merino Singles

Base O - Chunky Chainette
100% Merino

Chunky chainette is basically a cloud in yarn form.  It is the softest thing I've ever encountered but is surprisingly strong and sturdy, due to the chain composition.  This composition also makes it versatile as you can use larger needles to make the most of the meterage.  It goes further than you might think.  A single skein is more than enough for a hat or cowl, and a few will make you the most luxurious scarf or shawl ever!  I can only imagine the joy a sweater made from this would bring the wearer!  A true delight!

Base O - Chunky Chainette

Base P - Chunky Twist
100% Australian Merino

For those who enjoy a plied chunky, this lovely soft offering has a 2ply composition, and is a joy to work with!
