To make the roll, the sliptacks are removed and the burlap permanently stacked higher up on the frame, so that it can be rolled under the stuffing, which extends out over the frame. The tacking should be started in the center of all f°ur sides, be worked toward the corners, which can be thinned out if they become too fun. The actual process of forming the roll edge consists of a series of stitches at gradually lift and compress the roll as the stitching gets closer together, nether a straight or curved needle is used depends upon personal preference; s mserted at a lefthand corner, for example, about 1У2 in. above the row of 362 FURNITURE MAKING AND CABINET WORK Fig. 6.ю. Stitching a hard edge. tacks, and pushed under the roll to emerge about i in. inside the row of stitching that holds the two burlap layers together. The needle is then reinserted from i to 1У2 in. to the right and returned, so as to emerge to the right of its point of initial entrance at the front. Many workers content themselves with looping the twine over the point of the needle before it is pulled through this second stich, in order to lock it; others prefer to tie a slip knot. In any event, the twine must be pulled tight as the stitching proceeds around the four sides at even Fig. 6.11. Blind stitching. UPHOLSTERY AND SEAT WEAVING 363 intervals. As the work progresses the filling should be regulated, when necessary, with the icepick. As illustrated in Figure 6.10, a second row of stitches is sewed about y2 in. inside the first row, followed by a third row and if necessary, a fourth row, until the roll has been lifted and compacted to about a %in. diameter. Fig. 6.12. Reupholstering will save such chairs as this one. Double stuffing. After the hardedge roll has been stitched, a second layer of stuffing, such as moss or curled hair, is fluffed out and evenly distributed over the burlap covering to such an extent that when it is pressed down by the palm of the hand the springs cannot be felt. Over this a layer of thin burlap is tacked in place and the stuffing regulated if necessary. Long, irregular stitches through the burlap will prevent this second layer of stuffing from shifting. Final padding. A layer of cotton batting with its edges feathered out so that they w;ii ЫеП(] with the contour is covered with muslin tacked to the frame. Since this is the last layer under the outer fabric, it should be smoothed down carefully to prevent lumps or irregularities. Cheaper grades of furniture omit one or more of the operations described in the preceding paragraphs. A careful worker can often achieve highly satisfactory results with thicker stuffing and fewer layers of burlap. If time and expense are 364 FURNITURE MAKING AND CABINET WORK limiting factors, the amateur upholsterer can dispense with such operations as the situation demands. Fabric covering. The final fabric is applied much as the muslin liner except that it is tacked under the lower edges of the frame, and folded carefully so that it can be "blindstitched" at the corners.
