I made a bobbin lace bolster, I don't like running out of space.
I used
rolling pin
broken sewing machine, thread, scissors
3kg sawdust
an old cot blanket
calico
some polycotton for the cover
25cm diameter and 35cm long
I cut 1 rectangle 84.5 by 63 and two 28cm circles (I used a large dinner plate) out of calico you could cut 4 circles from polycotton and stitck together for the ends
the same from the polycotton (if you make the piece say 100cm you could tie both ends)
I sewed right sides together and then sew one of the circles in with calico and polycotton. Making the seam allowance smaller on the polycotton. I put a channel on the other end of the pieces to thread cord through
I put the sawdust in the calico trying to compact as much as possible. Hitting the cushion with the rolling pin.
Once the inner was stuffed I place one the other circle on top and drew the cord tightly .
I then wrapped a cot blanket around it and put the cover on.
I have created about 7cm of lace I find that it is harder to put pins in than polystyrene. maybe and old camping mat might have been a good idea or some oven glove inner
it works if a little bigger than I expected
