Don't store under glass
Bobbins should be stored out on a shelf or on a stand, putting them under glass, where there is little or no air circulating will cause blooming
Not just wood, but also bone bobbins
Remember, pewter inlay appears on both wooden and bone antique bobbins.
A Nasty History
Lead has a toxic history (sorry, couldn't resist the pun), from being included in the paint on toys being used as a sweetener in drinks. Yes, there was a history of adding lead to cider to make it sweeter leading to brain damage and death and is the origin of the jokes about 'country yokels'.
Lead can oxidise and start to have a white 'bloom' on it. This is a sign of 'lead disease'.
Keeping antique bobbins in airtight containers will cause blooming.
The first thing is do not touch this with your bare hands. Put on gloves.
If you find that an antique bobbin has developed blooming then follow the advice from the Western Australian Museum on treating lead bloom.
When I took my first lace lessons back in 1988 (in Willesden Telephone Exchange - long story), I was fascinated with the thought of making miniature lace (long before Ros Snowdon's books came out) as my mum was starting out a dolls house.
When we got our lace pillows and bobbins, we also got a copy of Pam Nottingham's little paperback and in there were a number of smaller pieces.
I showed one to my teacher and said that I'd like to work towards that piece. Her response? Oh, you won't be able to do that for years.
After 2 months of making worm bandages (whole stitch, 1cm wide and 30 cm long) I came to the conclusion that she wasn't the teacher for me.
I joined my local group and whilst they didn't offer teaching, they were all very supporting in showing me tips and tricks and helping me if I got into difficulties.
With lockdown, access to face to face tutors has become very difficult, so this group and the meet ups via zoom are a godsend.
If any of you have a piece that you have seen and want to work towards it, then shout out and we can help you break down the patterns you might want to work in order to get there.
And that piece that she said I wouldn't be able to do? Made it 4 months after I started.
From time to time I post on different groups and wanted to collect some of the advice that I give in one places.
