iphere.
I mufl here entreat leave to remark, that notwithflanding the
above directions are addreffed to men in the wooden way, yet
it is certain that the Upholflerer may avail himfelf from what
has been faid on the fubjeCt: for the coverings of the like
folids made of any kind of fluff, ought to be cut by the fame
methods, and fewed together in feams anfwerable to the joints
in wood: but the elaflicity or pliablenefs of fluffs, &c. makes
it unneceffary to cut them into fuch fmall pieces as is abfo-
lutely required in wood.

whole
Draw half the plan of the front, as Fig. 34, and divide
the fweep of the front into ten equal parts, as the figure
fhews. Next determine how much rake the knife-cafe is to
have from back to front, by which it will be eafily feen how
much the fwell of the front falls at that rate, as the diago-
nal line 10.1 fhews in the cafe before us. Draw from 10 of the
diagonal line a perpendicular at pleafure. From the feveral
