Here's a really easy DIY wreath that doesn't take a lot of supplies or time, or skills for that matter. All you need are some fake flowers and a hot glue gun.
Start out by separating the flowers from the stems/leaves. Most of them should just pop right off easily, but if not then just cut them. Arrange the stems around in a circle that's the size you want for your wreath. Wrap the wire stems around one another to secure them, but you can also use some glue to make sure that they stay. Then arrange your flowers around the stems evenly, securing them with glue.
I told you it was easy.
