ILLUSTRATION 233 (Hollow Spots).--The ground is worked in double crochet (illustration 220). These spots, which appear raised, consist of 5 treble stitches; they are worked in every other row at intervals of 5 stitches. For working them leave 1 loop on the needle, insert the needle between the 2 long sides of the last-worked double stitch, and work 5 treble stitches, always inserting the needle into the front part of 1 stitch of the preceding row. The first 4 treble are completed entirely without taking up the loop which was on the needle; with the fifth treble stitch only the 3 loops are cast off together by winding the cotton round the needle. Miss 1 stitch of the preceding row under the spot.
