Interplay of silk, linen and goldthread

Last week, I showed you the set-up of my little experiment with underside couching. Today, I'll show you the exciting results. Show exciting results? Hmm, you probably need to take my word for it. This is goldwork after all and it does not photograph well. But first I need to make a confession. When I first experimented with underside couching for the epigraphy conference early last year, I took a thicker piece of chevron woven silk as my base. You can read all about my stitching nightmare here. The bottom line was that I needed a rather strong/thick 3-ply linen thread for the stitching. This made the back of my sample rock-solid and hard to stitch through when ending my threads. I thus concluded that you would always need a rather thick 3-ply linen thread. The 2-ply linen thread used in the Middle Ages must have been something of a super thread to withstand the force of underside couching. Nope. Wrong. Let me explain:

Madder-dyed silk

Red 65 gsm silk

This time, I tested four different types of silk twill, two different types of goldthread and three different types of linen thread. They all worked. I only broke my linen thread once (!). Conclusion: my very first piece of red chevron woven silk was probably not suitable for underside couching.

What did I use this time?:
- "G" in the pictures stands for Goldschild 40/3 linen thread (3-ply).
- "B" stands for Bockens 35/2 linen thread (2-ply).
- nameless 26,5/2 bio-linen thread (2-ply) from Egon Heger.
- "RG" stands for real gold thread with a silk core (Stech 80/90 from Maurer)
- "G" stands for gilt thread with a polyester core (Stech 80/90 from Maurer)
- 65, 72 and 103 are the weights of the different silk twills I ordered from Sator
- one piece of madder-dyed silk twill lighter in weight than the lightest (red) silk twill from Sator.
- #22 chenille needle and 40ct Zweigart Newcastle linen base.
I worked two rows with each linen thread, six rows in total for each type of goldthread.

As said: all combinations work. However, I do have my preferences. Firstly, the 3-ply Goldschild and 2-ply Bockens linen threads are very round and stiff/hard. They don't compress easily. Whilst this probably is not much of an issue for underside couching, it is with normal couching. The linen thread pushes my goldthreads away from one another. In comes the more loosely plied bio-linen thread from Egon Heger. This thread is flat and compresses easily. Definitely my first choice! Added bonus of the 2-ply versus the 3-ply thread, the back of your embroidery is softer and it is now totally possible to end your threads on the back by weaving them in.

Blue 72 gsm silk

Petrol 103 gsm silk

The weight and actual weave of the silk twill also plays a major role. Again: it all works. However, the thickest silk twill (103 gms, petrol coloured) is my favourite. The "hills-and-valleys" of the twill weave are very pronounced and can thus be easily followed to accurately space your stitches. This pronounced twill pattern is also seen in the historical pieces and from the drape, you can clearly see that the historical pieces used a heavier weight silk too. The madder-dyed silk and the red silk (65 gms) were okay to work with too. However, I didn't like the blue 72 gms silk as I had trouble stitching back into the same hole.

Real goldthread in the back forming little arches when using the underside couching technique.

What I liked the best though, is the real goldthread with the real silken core. It is stiffer than the gilt thread with the polyester core. This means that the stitches form a slight arch (see picture above). The embroidery becomes more textured. Just like in the originals. Combine these little arches with the more pronounced "hills-and-valleys" of the thicker silk twill and you come pretty close to the historical pieces (see picture below). In addition, the real goldthread did not stress the silks or my linen thread so much. It was therefore easier to work with.

See how proud the threads stand off the fabric? Also notice the pronounced twill weave of the samite (Musee Cluny Cl. 20197).

So, why then did we switch from real goldthreads with a real silken core to gilt threads with a polyester core? Costs. Whilst a 10 gr spool of the "fake" thread costs about €14, the same amount of the real deal will set you back at about €64. I can now hear you think "well the difference in the pictures is not THAT spectacular, so why spend the money?". Me answers: but the stitching experience and the results ARE very different and better. It just does not show up well in a photograph. In my ever-quest to get closer and closer to the historical pieces, I have decided to use this real goldthread with the real silken core for the next run of my Medieval Goldwork Course (I hope I can get hold of enough of it). I am pretty sure that I will make a few more converts :).
