The green and red hats are knitted;the scarf and beige/gray hat are crocheted. The scarf is crocheted length-wise with a couple rows of mesh, then shells, then mesh--as many rows to achieve the width you want.
The beige/gray hat uses a different shaping than I have used on other projects. The hat is worked flat from the bottom edge to the top in single crochet. The shaping for the crown is achieved by crocheting across a row, leaving five stitches unworked and turning to work back across the piece. Then turning and working the next row including the five left unworked, turning and working across. This is repeated until the hat is the size you want. Sew the seam and cinch and fasten the top. I don't know if I'll use this pattern again, but it was interesting for a one-off. It is designed for a beginner and seems to be a good first project.
Please don't try to battle your way through my description!! The pattern is here and my project notes are here.
This pink/red hat is made from bits of Plymouth Encore stash with the crown having a touch of mohair. This photo doesn't show the pretty stitches very well. The details are made with slip stitches. You can see my project notes here and see the pattern too.
That brings us to this hat that appears to have a basket weave texture. The angle of the light in this photo washes out the neck section, but the texture continues over the entire hat. This pattern is fun and fast. See my notes for details.
Do you have any FOs this week? Wishing you a happy and blessed weekend!
