Most badges are sewn on, but some may be the iron on type. There are also products that are a type of glue that may be used to attach the badges. Regarding where to place the badges, it depends on which organization the Girl Guide belongs to. Girl Guides Canada say that the girl's program books should have an illustration for placement of the badges on the sash. They also have photos of the sashes at their online store. The troop leader/guider should be able to tell you where the badges go.
Epoxy is the best one.
Attach it with a glue
super glue fits perfectly. i think that cats should not be guard cats and you should get rid of your cats. cats are not good animals to have
E6000 glue works best :) You can also glue a small wooden circle or felt circle inside using the e6000 glue and then attach to the hair bow with regular hot glue :)
glue.
White glue is good for that.
Super glue
I would use a construction adhesive such as PL Premium
White glue is definitely the best for that.
You can use fabric glue or iron-on adhesive sheets to temporarily attach scout patches to felt. Make sure to follow the instructions on the product for best results.
An epoxy cement would be best for that.
