This stitch can be made using any size hook or yarn.

This stitch is made using sets of 3 sts.

This stitch is made in the round NOT back and forth in rows.

Also a very important note, the raspberries are made on the back or "wrong side" of the project your working on, so if your making a hat you will have to turn your hat inside out to get the textured side once your done making it, so please keep this in mind. 

It's easier to start this stitch if you have a solid row first, so make your round of single crochets (or whatever) before starting a round of the Raspberry Stitch. If you learn better by watching, please enjoy these helpful tutorials below.
