Here are the pictures of patterns 3 and 4 which are following the 2 previous ones to complete the design in Reticello of this pincushion.
Pattern n° 3
Start by straightening 3 threads starting on the right side, hanging in the middle and ending on the left side.
Cover the threads with blanket stitch to the left half.
Stretch 3 strands again by hooking into a blanket stitch on the right side.
Cover the threads with blanket stitch and finish the right side.
Straighten 3 threads again according to the usual procedure.
Start embroidering the blanket stitches to the middle of the stretched threads. Hang the thread in the bottom of the window to fix the threads.
Finish embroidering the blanket stitches.
Now, the pattern is complete.
Pattern n° 4
Stretch 3 threads from right to left as usual.
Cover them with blanket stitch.
Turn the work 180 ° and pass the thread upside of the work and pull it through the top right corner.
As before, stretch 3 threads and cover them with blanket stitch to the center. Straighten 3 other threads by hanging them into the bottom blanket stitches.
Cover them with blanket stitches.
Stretch 3 threads again according to the usual procedure.
Cover them also with blanket stitch. Be careful that the chain of the stitch looks outside (which forced me to make the stitch from right to left!)
Finish the pattern with blanket stitches on half of the top right threads.
