Not only great for halloween
As German natives, we do not (yet) celebrate halloween but have a lot of other nice occasions to masquerade. I did those felties for a witch party and they were favorites for not only the kids but also adults! They really get together veeeeery quick and easy. I clued half of them on top of hairslides, the other half was sewed on top of some plain hair ties. Worked out perfect! Especially the cats are worn regularly ever since.
One star less as I couldn't find any information on how to do the spider. I expected the felties to come out of the embroidery machine just as shown, but actually you just get the body and need to add some ribbon for the spider legs. Of course I had no black at home... Luckily I found some black fabric covered wire which I sewed from the back before glueing to the hair slides and liked it actually more than the "ribbon version". Anyway, if you like to do some spiders, please be aware to have have some extra material for the legs available!
