Next to the satin- and chain-stitches I think BUTTONHOLE-STITCH is perhaps the most useful for linen embroidery. Simple buttonholing is worked from left to right, setting the needle in and out at right angles to the outline, holding the thread down with the left thumb at each stitch while the needle goes over it. Both chain- and feather-stitch may be considered variations of buttonhole, the principle of the method being the same in each case, viz. working from left to right (or from the top downwards), holding the thread under the thumb for the needle to pass over as it pierces the stuff and comes out again at one ‘stroke.’

In ordinary buttonholing the stitches are placed as near together as possible: at a little distance apart it becomes ‘blanket-stitch,’ of which there are as many variations as the ingenious needlewoman chooses to make, but which are not appropriate to our present purpose.

To work the foliation marked B on the sampler, it should be slightly padded, exactly as for satin-stitch, and the ridged side of the stitch kept to the outline; round the inner curves, if a sufficient number of stitches are inserted, the ridge will stand up a little and accentuate the ‘eye’ of the curve very prettily. The firmness of outline obtained by buttonholing has caused it to be applied to the most beautiful designs for cut-linen work (see Illustration, [p. 82]), which may be carried out with any amount of detail without the least danger of its fraying or getting out of shape, and which will last and wear as long as the linen itself. The outline should be run round before working the buttonhole for this purpose, the stitches kept close together and drawn rather tighter than when intended to lie on the surface.

The inner outlines, also marked B on the sampler, are done in the same stitch, in the one case set in straight and in the other slanting. The tiny rosettes above are worked by setting the needle in at the same place at each stitch. By drawing the thread fairly tight, a small neat hole is arrived at in the centre of each; if the linen is very hard and strong, the spot should be pierced with a stiletto before working.

Another application of the principle is shown as a ‘filling’ stitch at C on the sampler. It is worked like one of the lace stitches, except that the needle takes up a bit of the linen beneath at each stroke (instead of ‘being in the air,’ as lace may be truly defined). An outline of chain-stitch should be worked first, as it provides a neat and convenient boundary for the rows of buttonholing to begin and end with. Bringing out the needle on the edge to the right of the worker, it is carried straight across the work to the left and set into one of the chain-stitches there; it is then brought out at the next chain, and the long thread buttonholed over till it arrives at the beginning of the thread where it was fastened on. The same process is repeated till the space is filled, the stitches in each row of buttonholing being placed between those of the previous row, and each row beginning at the left over the thread laid across from the right.

This will be seen clearly by the detail C, which is very much enlarged to show the working, but the rows of buttonholing are not usually much more than ⅟₁₆ of an inch deep. It combines admirably with chain-stitch for leaves, flowers, and even figures, the stems and small details being worked in chain, and the filling in this solid form of buttonhole, while features and the folds of garments may be clearly indicated by voided lines.

Feather-stitch, marked D on the sampler, may be considered another development of the buttonhole-stitch, the simpler forms of it being merely one, two, or three slanting buttonhole-stitches taken alternately from the one side and the other of imaginary boundary lines. In practising the stitch, until the worker gets accustomed to it, it is a good plan to trace real boundary lines, determining the width to be kept to, and two other lines at equal distances within these, as a guide for keeping the stitches all of the same size.

Feather-stitch by itself makes a very pretty border pattern, but it always seems a little frivolous unless it is subdued by an enclosing line of chain-stitch or buttonhole, with either of which it will combine most happily. The chain may be done first on each side (making, in fact, the boundary for width), and then the single feather-stitches taken from side to side into each chain in turn, being careful to pick up a tiny bit of the stuff on the needle, as well as the thread of the chain, at each stitch, otherwise it will be only a surface-stitch, which does not wear so well, though the appearance is almost exactly the same. If buttonhole be used for the edge, either it should be done slanting, to agree with the feather, or the latter should be worked in upright stitches to suit the buttonhole. In this case it does not matter which is done first, as the stitches go between and not into each other.
