The book suggests Pipers silks - 90/2 80/3 etc as the correct threads
for the prickings as printed. In Sandi's earlier book - Special Effects
in Bobbin Lace - the pricking guides say that if you use the Piper's
threads you should use the prickings at 100% (ie the same as the
Inspirations). This is also the guide for Madeira tanne 50 Gutermann
silk thread.
I've never seen 90/2 Pipers' silk, and their website doesn't list it
either.
Brenda's book says that the Pipers silks recommended have 27-30
threads/cm but that Madeira 50 has 39. Madeira 30 has 29 threads/cm in
Brenda's book but Sandi's Special Effects suggest a pricking
enlargement to 105% if tanne 30 is used.
Yes, my measurements of the Piper silks were:
spun silk 80/3 = 27 wraps/cm
twisted gloss 80/3 = 28 wraps/cm
gimp 90/2 = 30 wraps/cm
gimp 90/3 = 27 wraps/cm
so all of a fairly similar thickness.
Madeira Tanne 30 = 29 wraps/cm so again a similar measurement.
Madeira Tanne 50, which I measured as 39 wraps/cm is quite a bit finer.
My question is
Are the silk threads squashier when used in bobbin lace so that the
extra threads can squeeze themselves into the space or have I totally
misunderstood Brenda's work!
Yes, silk is usually a bit squashier than cotton though it does
depend a bit on how firmly or otherwise it is spun. Any thread gets
less squashy if it is firmly spun.
On the Piper's website their price list includes a list of comparable
cotton threads. Both the 80/3s and the 90/3 they compare to Madeira
Tanne 30, which I would agree with, but the 90/2 twisted gloss they
compare to Tanne 50, Mettler 60/2 and Crochet cotton 80!!! Tanne 50 is
finer than the 90/2 at 39 wraps/cm and Mettler 60/2 finer still at 46
wraps/cm. Crochet cotton 80 whatever that may be (Coats? DMC
Cordonnet? Special Dentelles?) is likely to be around 30 wraps/cm
I thought that where were 99 wraps per cm
in Yarn A and the pricking said use yarn B, if yarn B was within a
reasonable number of wraps of A it would work
Yes it should do although substituting a cotton for a silk will make
quite a difference in the feel of the finished lace.
and that otherwise you
had an adjustment fact or to apply based on 99 X A/B (or 99 X A2/B2 ?

please answer this one too, someone, again!).
Unfortunately it's not quite as simple as that!
For torchon you should be able to fit 12 threads between footside
pinholes, and for point ground laces 10 threads. There are tables in
the front of my books for the different size grids. For sectional
laces, such as Milanese, it has to be a bit more flexible, depending of
course on how curved the braids are and how many pairs you are using in
relation to the width of the braid, but about 8-10 thread widths
between pinholes is a rough guide. Don't try to measure the distance
between 2 adjacent pins - find a straight run and count the spaces
along 10mm.
A thread which measures 30 wraps/cm will fit 30 thread widths between
pinholes which are 1cm (10mm) apart. If the pinholes are 5mm apart
then 15 threads would fit between them (and the thread would be too
fine for that pricking). but if the pinholes were only 3mm apart the
same thread would only fit in 9 times and would be about right, but if
the pinholes were 2mm apart it would be too thick as only 6 threads
would fit between.
An approximate guide for Milanese (based on measurements from Pat
Read's books) is:
3 spaces/cm = 27 wraps/cm thread
3.5 spaces/cm = 30 wraps/cm thread
4 spaces/cm = 32 wraps/cm thread
5 spaces/cm = 40 wraps/cm thread
6 spaces/cm = 50 wraps/cm thread
7 spaces/cm = 56 wraps/cm thread
Of course personal preference also comes into the equasion; you might
want a thicker thread to give a substantial and dense appearance or you
might want a lighter, airier appearance to your lace.
