In netting a round net, the loop upon which the first meshes are made can be afterwards tied up tightly to form a bottom. Or the first meshes can be cut away, the short cut ends pulled out through the inner bights of the second row (that is, the now inner row of whole meshes), and a grommet worked if a circular hole is wanted; or the ends can be drawn together and tied with a separate piece of string. To prevent crowding of meshes at the bottom of a round bag it is usual to commence with about six meshes for the first row, making the first as small as possible at the tapered end of the mesh, the last two being worked loosely at the broad end; the first stitch of the second row will then be nearly regular in size, and in the third row all will be even. But in this row, if the net was commenced on six meshes only, stitches must be added; to do this, work two meshes on each loop of the former row, or two on every other loop, according to the shape of net required. in this way add meshes in any row where it is desired to increase the diameter.

It is not often wished to decrease the diameter of a round net, but if required to do so, pick up two meshes on the needle at once and hitch together in one; each time this is done one mesh less will, of course, follow in the succeeding row.
