Picking Sheds and Passing Bobbins

A couple of days ago in the Fringeless class
someone asked: 
​"How do you do that cool picking-up-the-sheds thing?"

The class includes a number of weaving videos
including a rather long one
in which I weave most of the piece in the photo below--
chatting all the while about what I'm doing and why I'm doing it.
At least I talk about building shapes.

Apparently I don't talk much about 
what I'm actually doing to open the sheds
and pass the bobbins however,
so I thought I'd try to explain further here
in case those of you not taking the class might find it useful too.

As I may have mentioned before,
I adopted both techniques--
first  bobbins then finger picking--
after a decade or more of  butterflies, beater and treadles.
Once again, it was Archie Brennan who made it seem worth a try.
With a big pipe loom warped and ready
I committed to weaving the entire thing
 (Hang Up and Draw first tapestry on the linked page)
using only bobbins.
 I started with leashes as well
(long heddles you can grab and pull), 
but before long found myself finger picking both sheds
so haven't bothered with leashes or butterflies since. 

Anyway, yesterday I decided to try to film myself weaving.
Without Rebecca Mezoff and her
excellent eye and amazing camera
the following two videos are not the snazziest thing in the world,
but here they are nonethless:
1-over and back, over and back, at 'slowed down normal' speed
2-over and back in super slow motion
3- a rather wordy description of what I think I'm doing
(which may, or may not, be what I'm actually doing
but is the closest I can come)
4. Some assorted comic drawings which might help too

 EDIT!!!!!!!OH NO!  The videos vanished.  SOSOSOOS sorry 
I have no idea what happened but will try to figure out
or fine another video solution
They take HOURS to upload so it'll be a while I'm afraid.
After all my boasting and that marvelous feeling of doing something cool
Maybe words and comics are the best after all
​SIGH.
​

The Wordy Description
-Bobbin in right hand going both ways, always
-Shed picked with left hand going both ways

OPEN SHED
(in this case weft moving from left to right but not always)

LEFT HAND:
(always picking up the warps from left to right no matter which direction the weft is going)
-decides which warp to pick up first,
- slides up that warp towards the shed sticks where the opening is wider
-fingers slip behind three to five raised warps
-pull them open
RIGHT HAND:
-slips into shed just opened
-passes bobbin through the space behind the warp and back into the same hand
(bobbin now in front of the warp)
-pulls slightly on the weft while 
LEFT HAND:
-releases warp threads
-drops down to grab the end of the weft
-adjusts weft tension
(leaving enough weft in the shed to make a nice bubble)
-holds onto weft while
RIGHT HAND:
uses bobbin to tap weft into place.

Note: finger picking techniques are the same no matter the loom you're working on. This image from my comic, Backstrap Dialogs

PICK SHED
LEFT HAND:
(scooping up warps from left to right no matter which direction the weft is going)
-chooses  warp at the edge of section to be picked up,
-pushes back against the open warp to the left of that warp
-reaches back and grabs desired "back" warp between thumb and middle finger
- pulls that warp forward, holding it on forefinger 
-moves one warp to the right, over the next open warp 
-pushes back against that open warp as before to make space to grab next "back" warp
 continuing in this way until 3 - 5 warp threads (about one inch worth) have been grabbed.
-pull to open that section of the shed
RIGHT HAND 
​​-slips into space just opened
-passes bobbin through the space behind the warp and back into the same hand
(bobbin now in front of the warp)
-pulls slightly on the weft while...
LEFT HAND:
-releases warp threads
-drops down to grab the end of the weft
-adjusts weft tension 
( leaving enough weft in the shed to make a nice bubble, which is easier with pick shed as the released warp adds its own tension)
-holds onto weft while
RIGHT HAND:
uses bobbin to tap weft into place.

Backstrap Dialogs (detail p. 39) -- same technique for passing the bobbin, using string heddles as leashes instead of finger picking the second shed.

All of this takes a LOT Of words,
and I generally find Comics to be a more efficient medium
than plain text, but hopefully the videos make things somewhat clear.
And alas, if I had to draw an entire comic 
for every blog post, you'd get one a couple of times a year!

NOTE: Bobbins
Still REALLY happy with both sets of new bobbins I wrote about here
Both makers are HIGHLY RECOMMENDED

NOTE: Sett
​ The warp on the loom in the videos above is sett at 10 epi,
8 epi is easier and smoother (more room to teach and grab)
but much of this depends on the size of your warp 
and the size of your fingers.
If your fingers are large and/or you like to work at closer setts
I  recommend some kind of shedding device for the pick shed --
Leashes and String heddles (very short leashes), are both excellent.
I describe the latter in Backstrap Dialogues,
and will put a detail below, which should help.

So that's it for now --
EXCEPT! that for those of you not on Instagram
I wanted to include a photo
of  the finished running shoes
I was working on last week!
SO happy.
