Negative and positive space within sculpture

I wanted to experiment with the positive and negative space of the new work, but not be able to see the negative space is difficult to visualise how this would work.

It’s hard to look at the weave and not see how it will look when the plaster is no longer there. Being able to visualise the finished piece is becoming more and more difficult.

If I can’t see the negative space or void in the sculpture how will I know that it creates an interesting juxtaposition with the positive or the woven surface of the sculpture?

Do I weave and hope that it works when cast? There must be a method of allowing me to experiment with this combination without waiting until the work has been cast.

Results of weaving onto plaster forms

Weaving Experiment No.53 - the opening is very small in the centre and very difficult to get my hand into the form to apply the weaving. Also the small gap in the centre could be an area that an air bubble could become trapped when the work becomes invested ready for casting. I think I should discuss this further with the foundry.

Weaving Experiment No.54 - This is not working, the weave is not sitting into the concave areas of he plaster carving. I could potentially drill a series of fine holes through the plaster and pass fine cotton through as a way to pull the weave into the concave areas and hold it tight against the plaster surface. The tiny holes, however could allow air to be trapped and this may cause explosions in the casting process.

Weaving Experiment No.55 - Success! The shape has worked very well with the weaving applied over the surface and a taught weave was achieved. Thick areas could be created, fine open areas could also be applied that fits snugly against the plaster surface.

Moving forward, if a hole is within the design it should be large enough to allow the weaving to easily pass through the and also to allow fingers to be able to work in the void.
Shapes should be convex and not concave as the weave will not pick this up, unless I can find another method of weaving wax onto a concave area.
