Why roving?

So far, I have knit most of my covers, longies, and shorties out of roving instead of yarn. I certainly can knit with yarn (do it all the time!) but I think roving has some unique advantages over yarn.
First of all, what is roving? Well, roving is yarn "one step back." Here's how you get yarn:
Step 1: Shear the sheep
Step 2: Wash the wool (sheep are actually pretty dirty!!)
Step 3: Card the wool-you can think of this as getting rid of the knots in the wool. It does the same thing as running a brush through a person's hair. This makes all the wool fibers "lay" in one direction. When you do this, you can also make long "strands" or "batches" of wool. The wool is now considered roving.
Step 4: Dye or paint the wool-to make it pretty colors!
Step 5: Divide the roving off into strands
Step 6: Spin the strands into yarn (basically, yarn is twisted roving).
So, why roving instead of yarn? Several reasons come to mind:
1. Knitted roving is WAY softer than knitted yarn. The reason for this is that the twisting process that turns the roving into yarn puts tension on the roving, which makes it less soft (and sometimes scratchy!).
2. Because roving is "brushed sheep's wool" it somewhat "sticks" to itself, so fills in the gaps a better than yarn.  You have the advantages of felting without actually felting-so you have stretch AND "stick" if you will.
3. Roving breathes and absorbs better than yarn.
4. Because I can hand divide it, I can really customize everything about the garment for you. Do you need something super thick for your heavy night wetter? We can do that! You want something thin and light for daytime play? That's completely possible as well!
5. Because there is one less step in the process, roving is a little less expensive than yarn, which allows me to pass the savings to you!
Some differences you will see with a cover made of roving instead of yarn:
1. It will be a little "fuzzier." Again, this is because the strands have not been twisted. Now we are not talking about something that will shed all over the place or be crazy fuzzy (see photos below)! But there is a little bit of a "softer" look to them.
2. Because I hand divide off the sections to knit, some rows will be a tiny bit thicker than others. Nothing crazy, and it certainly doesn't impact the function! You can think of it as the difference between the way that true handspun looks versus machine created yarn when knitted up. Honestly, you wouldn't notice it without looking VERY closely.

Shorties made of roving. I think you can see the "soft/slightly fuzzy" quality better in this photo.

Longies made of roving. Just as with any fabric, appliques can be added!
