The next two borders in the needlepoint reproduction of the Bath Mosaic combine Tent Stitch and Backstitch. Each will be shown as a straight border and then as the corner.
The first border is made up of Backstitched squares with Tent Stitch squares in three colors of silk inside them. Remember: blue squares – blue Needlepoint Inc 325, red squares – terra cotta Splendor S925, green squares – gray Splendor S920. Being the border 3 threads rom the previous border.
The terra cotta and gray stitches form “L’s” in one corner of the square while the blue is in the other corner. This means that at the corners, the blue squares will meet up on only one side. The corner chart, above, shows the placement of the border in relation to the previous border.
The next border (the fifth counting from the center, is made up of diagonal lines of all three colors. The border is outlined in Backstitch and is two threads from the previous border.
Because these are diagonal lines of stitches, two of the corners will have long lines of stitches, as seen above.
