I designed this hat in December 2016 as a present for my niece and surprisingly, probably the color combination and the shape, it caught a lot of attention and recently I have seen many colored variations of this slouchy hat around the Czech facebook crochet groups.
It is called “homeleska” in Czech. No one knows where this name came from. It remains me more of a Smurf hat but either or it is quite nice and easy project almost everyone can easily do. It is perfect for spring or autumn season because it is made of double bamboo yarn. I love this type of yarn because you feel warm when it is cold and it somehow cools you when it is hot. I mean hot, but I am talking about the temperature around 15 degrees :-). Plus it is natural fiber, it has antibacterial and antistatic features so it is perfect for children.
I chose white/cream and navy blue combination and it looks really nice, trendy and unisex.
Useful tips (my lesson learned shared with you):
this hat is crocheted from the top, but for some reason, the hat circumference divided by 3.14 = the diameter of the “hat” circle did not work, so it is better to try, how much stitches you would need for the final circumference and count from that
better to be slightly tight around the head, bamboo is similar to cotton in a way so it stretches/become loose
I added stitches in every second row, so it makes the circle grows slowly and the final result is better
For the adult size you would need two balls of each color and the hat is slightly heavy
Before crocheting the ribbing, it is useful to try the hat on. It should be slightly loose because the ribbing makes is tighter. Otherwise you may end up with a smaller size.
Time to times count the stitches, as the rows switch (DC and BPDC) you might unwillingly add stitches without notice
Everyone is using different tightening during crocheting but here are my tested measures and stitches for different sizes
45-46 cm = final 58 DC, length 22-24 cm
48-50 cm = final 64 DC
52-54 cm = final 68 DC, length 28-29 cm
54-56 cm = final 72 DC
58-60 cm = final 80 DC, length 33-34 cm
Conversion to inches here.
So lets start, spring is around the corner.
Easy slouchy hat, adult size, head circumference 55-56 cm
