Pineapple half drop stitch
This canvaswork stitch is worked in vertical columns of crossed blocks of pineapple stitch, with a half drop to each column. Pineapple stitch is a padded square stitch with a couched diagonal cross.
Method
Make four vertical stitches across four threads of the canvas to make a square block.
Next, bring the needle up one thread across from the top left-hand corner and take it down one thread across from the bottom right hand corner.
Make a second diagonal stitch across the block from the bottom left hand corner to the top right-hand corner. Always make the top stitch of the cross in the same direction.
Tie down the cross with a horizontal stitch across the centre of the cross (over one vertical canvas thread). The stitch will appear diagonal because of how it lays over the cross.
Make the next block in the same way directly beneath the first, and continue in a vertical row.
For the next row to the right, begin the block two threads above the lower right-hand corner of the last block. The cross of the next row should tuck under the vertical edge of the previous row.
