One of those, however, used in each angle, as number 2 of Figure [138B], is only temporarily fastened at first. Commencing with section 1 cover the walls first with shaker or canton flannel lining tacked smoothly and evenly on the strips, as Figure [138]; next spread the covering out, attaching it temporarily to the top strip until you get it in place, then commencing in the centre at X tack each way, keeping the edge straight and tight, but not stretched. Drop a plumb line from the top over the centre seam and stretch the seam down as the line indicates, tack it temporarily, and do this with all the seams; now pull down half way between the seams and tack permanently, halve the two spaces thus made and tack again and continue halving and tacking until the bottom is all tacked in place, taking care to stretch the goods so that the pattern is perfectly straight at the bottom.
Now stretch each side and tack it closely into the angles, as the tacks on strip number 1 must be covered by the thick edge of strip number 2, Figure [138B]; now take the loose strip number 2 which was removed to allow the tacks to drive close up into the corner.
After matching the exact part of the pattern which is to turn in of the next section, tack the marked edge of goods to the back edge of strip 2, nail the strip in place so that there is no gap between the two angle strips. Cover the wall with lining and stretch the cover across from the tacked side, fasten it temporarily and then commencing at the side which is fastened permanently tack across the top, keeping the top tight, but not stretched, stretch down and plumb the seams and finish as before.
The detail of procedure for Figure [137] would be as follows: Section 1 tacked all around. Section 2 back tacked at B stretched around C and to tack at E. Section 3 back tacked at E and stretched to F. Section 4 backed tacked at F and stretched around G to H. Back tack Section 5 at H, stretch to I. Back tack 6 at I, stretch to J. Back tack 7 at J, stretch around K and L to M. Back tack 8 at M, stretch to N. Back tack 9 at N, stretch around O to angle P. Back tack 10 at A, stretch around S to R. Back tack half of 11 at R and half at P, and stretch each to join at L, which has been chosen as the smallest place for a join to be made by hand.
