This tutorial was originally published on vampy.co.uk all the way back in 2009, and has been updated slightly for use here.
This tutorial will show you how I use my drum carder to blend different colours and fibres to make batts. If you don’t already know how to use your carder, check out my first post on the subject about the basics first, as it contains a few tips on how to get the best from your carder.
In this tutorial I am working with commercially dyed merino tops, and sparkle in the form of trilobal nylon (sometimes called firestar) and angelina. Any commercially prepped fibre can be used in this way. If you are wanting to blend any fibres with raw fleece, it’s easiest to first prepare the fleece as shown in this tutorial before moving on to blending.
I won’t be talking about colour or fibre choices, simply the mechanics of using the carder to get the results you want. There is plenty of information online about which fibres work well together, and the book ‘Color in Spinning’ by Deb Menz contains great in-depth information and explainantions about colour theory and selecting colours for your fibre.
My first batt is for a swap partner who previously won some batts in a competition I ran. She asked for another batt that would go with these existing batts so she could use them all in a project together. I decided to go with deep reds and black, with a little yellow, and lots of gold sparkle. I wanted the batt to be fairly well blended, but not a completely even colour all over. Here are the colours I decided to use:
(as an aside, the table I use for my carding in these pictures is a knitting machine table, it’s exactly the same width as the carder, and has space either side for my fibre and tools…and it cab easily fold down so it doesn’t take up too much space)
Once you have picked your fibre, you need to get it ready for carding. My eureka moment with this came when I realised that commercial tops aren’t a long sausage of fibre as I’d originally thought, but are in fact a flat sheet of fibre, folded or rollled up. To spread the fibre out to run it through the carder, you just need to find the join, and flatten the fibre out:
This will give you a lovely sheet of fibre with all the individual fibres running parallel. Place the fibre in the feed tray of your carder:
You will notice that the fibre doesn’t reach the edges of the tray. This is where your other hand comes in, as well as using it to gently guide the fibre into the tray, you can also stretch the fibre out so it fills the full width of the drum. Once you’ve got it started, it will continue to follow the same path, so you’ll only need that hand to guide rather than spread the fibre too. Remember not to pull on the fibre, just hold it gently and guide it along as it gets pulled in.
I normally use around a 30-50cm length of tops at a time…shorter if I want a more blended batt, so I can get thinner layers of different colours.
When you’ve finished with the first section of tops, repeat the process with your other bits, alternating colours each time. When you come to add sparkle, you won’t need to use anywhere near as much as you would do wool. In this batt I put in 3 or 4 layers of gold trilobal nylon, using about this much each time:
Even this fairly small amount adds a lot of glitz to the batt…here it is on the carder:
After a few layers of fibre, the carder will start to look full, the fibre on the main drum will be getting close to the top of the teeth. In fact, it’s nowhere near full, it just needs squishing down. Run a bristle hairbrush over the drum while turning the handle, and this will compress the fibres and allow you to add more. The below pic is of the drum before and after going over with the brush.
Keep adding more layers in different colours until you’ve used up all your fibre, or until the drum is so full that even brushing it won’t allow you to fit any more on. My carder will hold up to around 110g, though I try not to make batts much larger than 80g.
When removing the batt, use your doffing tool to free a small amount fibre each time, working your way along the space between the teeth until the whole batt is no longer joined.
Take the fibre, and roll it up away from the join. If you keep your hands close to the drum when rolling, there shouldn’t be any stray fibre remaining on the drum.
The batt currently looks a little messy and not that well blended, so it’s time to recard it to even it out. Tear a thin strip off the edge of your batt:
The strip should be about 1/3-1/2 the width of the feed tray, or less if it’s a very thick batt. Take the strip and pull it apart from side to side, to thin it out, and make it the full width of the tray:
Recard this strip as before, gently guiding it in with your hand while you turn the handle.
Repeat this process, tearing off strips and spreading them out, then carding them. When it’s all done, remove the batt:
This is the effect I was looking for…blended, but not uniform, so the final yarn has patches of different colour. If you want a uniform batt, then repeat the stripping and carding process again until you are happy with the result. If you are blending different fibres (such as wool and silk), you will probably want to do 3 or 4 passes through the carder in total to get a smooth blend so you don’t come across patches of a single fibre when you are spinning.
For the next blend, I wanted to make a batt that faded from one colour to another across its width, with a little sparkle added. Here are the colours in the sequence I wanted:
When I first started carding, I would have torn off thin strips of each colour and laid them side by side on the drum. While this works, it’s fiddly, and you don’t get a nice shading from one colour to the next….so these days I use the below method instead.
Card your fibre, as above, in layers. Start with the colour you want on one side of the batt, and work your way through them. I split each colour of roving in half, and put a small amount of angelina fibre inbetween the two layers of the same colour…green angelina with the green shades, blue with the blues.
When your batt comes off the carder, it should look something like this, a solid colour each side, with layers of other colours in between:
Now you have to recard the batt to get the colours running across it.
As before, tear off a thin strip from one side of the batt. This time, rather than spreading it out flat, turn it on its side, so the layers of colour are running from one side of your strip to the other:
Repeat for the rest of the batt. Don’t worry too much if the colours don’t match up exactly from one layer to the next, this is what gives the final batt the shaded effect. When you’ve finished, your final batt should look something like this:
I hope this gives you some inspiration and the confidence to try making your own batts. Don’t be afraid to experiment with colours and textures, you may come up with something you really love!
