Show and tell is quite a popular feature at my local Machine Knitting Guild. Here a couple of items.
The scarf is a bias knit. Cast on,on one side of the machinebed. Knit 2 rows, cast off 1 stitch on the left side, cast on 1 stitch. Repeat until you are satisfied about the length.
The sweater was a commission that the knitter accepted. The yarn was supplied. It was done on the Chunky Knitting machine, the lace was hand manipulated. Very time consuming.
