April's group dye pot was Osage Orange. In this case I was using sawdust, contained in an old nylon stocking which soaked in the dye pot for 24 hours followed by heating to close to boiling for about an hour prior to yarn being added. Below are some small sample skeins showing the different effects possible with various pre-mordants.

Madder is one of those dyes that is supposed to give red, but in my experience, not very often. After reading some books and watching a few videos, I learned that if chopped madder root is soaked, and the water discarded then it supposedly gives better reds because it removes more tannins that are concentrated in the bark of the root, and in addition, adding calcium carbonate (chalk) is also supposed to give better reds, especially if done after the madder has been chopped during heating. So I started with dried chopped madder root.

More skeins that are rather bright, and in some cases a little mottled from bleeding during rinsing from JB. These were re-mordanted with alum and then rinsed well.

Transformations can be so magical. Two shots below of a scarf pre- and post-overdyeing with logwood. Below that is gray-green produced by over-dyeing skein originally dyed with yellow onion with logwood. The rule of thumb I've developed over the years is that if you don't like the color, overdyeing in blue will make it better.

In the usual way of things, if you want green from natural dyes and are using indigo, typically you dye with the plant material that will give yellow followed by over-dyeing with indigo. The reason being that indigo tends to be a very strong dye and it is easier to control color and depth of shade by using multiple dips of indigo until you have the green you want. In this case the yarn had been dyed with indigo by a fiber friend who told me it was crocking badly and wondered if I could try dyeing it with the leftover yellow onion dye bath from one of my on farm dye days. Thinking this would be a fun experiment, I readily agreed. My first step was to wash out the excess indigo using synthrapol - it took a lot of rinsing, but eventually the rinse water was much lighter. I then gave the skein a bath in 20/80 white vinegar/water which yielded a clean rinse. The next step was to heat up the leftover dye bath and also add back in the fine mesh bag containing the onion (removing the bag of wet plant material and allowing it to dry prevents mold). The yarn was simmered for 30 minutes and allowed to cool down in the dye pot overnight prior to final rinsing. The two pictures below show before and after - definite darkish green with blues. The small skein in the lower second picture is one that I simmered after the indigo skein had been removed; the purpose was to see if I could still get yellow out of the dye pot, which clearly was the case. The great thing about this kind of experiment is that the yarn goes back to the original owner and I don't have yet another dye experiment skein for which I don't have a purpose.

This was the first time I've used Brazilwood in quite some time and certainly the first time with this much variation in preparation and handling the pot. First I soaked the Brazilwood sawdust (3 oz) overnight in a nylon stocking to contain the chips/sawdust; then I boiled it for 1 hour. Then I added pickling lime, i.e. calcium hydroxide (about 1/2 oz), plus a stick of ground up chalk to a pot of hot water, and then the dye liquor and bag of chips. The pH at this point was close to 9.0. A mix of fibers was added (mostly wool), some of which had been pre-mordanted with alum or copper. Then the bath sat for about a month prior to being acidified with citric acid; interestingly I had no problems with mold growing in the pot during the month it sat idle. I did take the precaution of removing the bag of Brazilwood chips and letting it dry out after we had finished with the first basic pot, and then put it back in the pot just prior to acidifying the pot. The pH just prior to acidifying the pot was about neutral and after the addition of citric acid (~2 oz) it went to about pH 5. Below is a picture of the resulting wool yarns. From left to right, it is alum and copper pre-mordant with basic 1st pot, then alum and copper pre-mordant in the acidified 2nd pot. The two things that are most striking to me are the range of color and that their is very little apparent difference between the alum and copper pre-mordant yarns.

I truly love bulky yarn and have had a wonderful time dyeing and then knitting and crocheting two projects out of some super bulky yarn that I purchased from Heelside Farms in Four Oaks, NC. The first project was my second knitted hat in the Collapsible Cloche pattern which can be seen on my Ravelry projects page. This was supposed to be for me and ended up being for Gary because it fits and is convenient to grab and wear on cold winter mornings out taking care of critters. Since I had plenty of yarn left for another hat this seemed like it would work out just fine. Having decided I wanted a crocheted tam, I found a pattern that seemed ideal - Super Bulky Tam by Candice Veazey. The only thing I didn't reckon on was that the size of yarn differed somewhat from the pattern which I faithfully followed to produce the first tam pictured.
