Knitted on 2 needles.
K = Knit
St(s) = Stitch(es)
tbl = through back of loop
RS = right side
Tension (gauge) isn't important but if you use needles one or two sizes smaller than recommended for the yarn, you will get a more closely knitted flower. (I used Baby Cashmerino and 2.5mm needles.)
Using blue, make slip knot on left hand needle and cast on 2 more sts (3 sts in total, RS facing).
Cast off 2, knitting the last st tbl (1 petal made).
*Slip the remaining stitch back onto the left hand needle, keeping the RS of knitting facing you. Do not turn the work.
Cast on 2 more sts.
Cast off 2, knitting last stitch tbl (this just makes a firmer straight edge).
Repeat from * until you have a line of 5 petals.
Fasten off leaving an end a few inches long. Thread this end onto a sewing needle. With the right side of the knitting facing you, use the needle to gather the straight edge, being careful not to twist the knitting. Draw up to form a flower and secure. Where the two end petals meet, secure with a tiny stitch.
It was designed a s a forget-me-not, but as a general small flower pattern it could be made in any colour.
