I stumbled across these and thought they would add a different texture for our historical rooms. Having found these images below I thought I'd research a bit further and you'll find some descriptions on how to make various types of wall pockets. Another name for a wall pocket was a 'catch-all'.
Descriptions and Directions for wall pockets. (I didn't include the images but they are referenced in the excerpt.)
WALL-POCKET FOR LETTERS, CARDS, ETC.
Take a piece of white card-board, or better still, the lid of a large handkerchiefbox, with handsome plate; cut a piece of card-board of same width and half again as high; fasten together at bottom with muslin hinge, and pink entirely around, perforating each scallop with one or more holes. Make end-pieces of silk or reps, with elastic let into a shirred ruffle at the top and plaited closely at bottom. Obtain four of the pretty card-chromos of flowers or views, which pink entirely around, and making perforations at each side, tie them with bows of bright-colored ribbons to 'each side of top and front of pocket for the reception of cards; suspend by broad ribbons that match the bows
WALL-POCKET FOR DUSTERS, ETC.
Take a piece of heavy pasteboard, eight inches high and ten inches long, which cover neatly with brown linen, pasting colored paper-cambric upon the wrong side; cover another strip of the pasteboard, three inches longer and seven inches high, with the linen, embroidered with scarlet thread. Make a bag
a half yard long, and sufficiently wide to be gathered with a shirred ruffle around the case; gather at the bottom, closely, and finish with a long scarlet tassel made of zephyr; sew heavy, scarlet woolen cord around the case with tassels at each corner, and cord and tassels fastened at each end for suspension.
WALL-POCKET.—WITH A SMALL IRONING-BOARD.
Materials: Gray linen, white flannel, red worsted, medium-sized cord, worsted braid one and one-fifth inches wide; red zephyr worsted, and silk. A board, fourfifths of an inch thick, twenty inches long and eight inches wide. This pocket is exceedingly handy in a bed or dressing room, as it contains a little ironing-board on which little things, such as collars, cuffs, ribbons, etc., may be ironed. A
small pocket at the top contains an ironholder. Our model requires three pieces of linen, eleven and one-fifth inches wide, the one for the back part twenty-four and two-fifths inches high; that for the large pocket twenty inches high; that for the small pocket seven and three-fifths inches high. The upper corners of the back part and small pocket are slanted off, beginning at a distance of four inches from the top, and leaving it six inches wide. Both pockets are rounded at the top into a deep scallop, bound with braid, and edged with a rushing of braid. They are further braided with soutache, in the manner represented in the engraving. The small pocket is sewed to the back part first, and then the long one; the whole is then bound all around with braid, and decorated by a rushing of braid. Two loops of red cord, each one inch long, are fastened to each corner of the top, and serve to hang the pocket up. fig. 11 represents the ironing-board, and shows the manner in which a flannel cover, twenty-two and two-fifths inches long, ten and two-fifths inches wide, scalloped all round with red

the board. The iron-holder consists of a bag, five and three-fifths inches long, and four and two-fifths inches wide, stuffed with batting, and covered by a piece of flannel, scalloped all round with red worsted; the flannel must be cut three-fifths of an inch wider than the holder all around, and fastened to it with fine, invisible stitches.
