For my mom's birthday I knit her two flower shaped bowls and felted them (washing wool in a way that purposely shrinks it).
I used this pattern from Ravelry and I used worsted weight wool leftover from other projects. They knitted up looking like floppy hats but when you felt the wool it tightens up to form a bowl that you can shape as it dries.
I had some issues with this blue bowl. The outer edge was done with Jacob wool that I picked up at a local fiber festival. It didn't felt like the other wool.
See how you can see the stitches when you stretch the fabric? You shouldn't be able to see that. I washed it a second time trying to felt it further but it still looked like this. So this flower will have droopy petals.
They were fun and pretty easy to knit up (though I really can't stand K3tog!). I think I'll make myself a few of them one day.
