Dear Jacqui,

I admit that I purchase my wire and plastic mesh in the US, but the 
company I deal with, listed below, has all grades, thicknesses, 
aperatures and also plastic versions.  These types of companies are 
called wire cloth companies.  Perhaps you can search for this in the 
UK or EU.

it is worth a try to get the opening you require for floting, that is 
after all the most important part of a flotation machine.

>Dear Stephanie,
>We've tried various methods over the years although only with plastic
>mesh as I don't know of a British source of wire mesh. We use plastic
>washing up bowls as these often have a convenient ridge around the base
>that is easy to cut against when removing the base.
>We've found the most reliable to be a double set of stitching, each with
>saddle stitch, using either nylon fishing line or a heavy linen thread.
>For the non- sewers, saddle stitch uses two needles and threads; pass
>one up through a hole and the other down through the same hole, pull
>tight and move onto next hole.
>We use a fine mounted needle heated in a Bunsen to  make the holes but
>you have to be careful not to make them too large. Alternatively use
>robust leather needles and a pair of pliers. 
>As long as the mesh is cut quite closely to the outer line of stitching
>the sieve is easy to clean of the little material that gets caught under
>the mesh.
>We have tried all sorts of materials to seal this edge but they are
>either rigid and quickly break/flake or are flexible and get soft and
>sticky when we put the bowls in the ovens to dry the flots. A thin layer
>of ordinary gloss paint works quite well for the finer mesh sizes and I
>have a 300 micron sieve made more than 10 years ago still in good
>working order - it has only had 'one careful owner' though and not a lot
>of work recently! The mesh is white and by using pale coloured bowls
>(luckily 'fashioinable' today!) it is easy to check for possible
>Look forward to seeing what other methods have been used....
>Happy sewing,
