If you like bobbles, you may want to try the bobble cast on for your next project. A great way to add a decorative edge to anything that suits your fancy.
If you want to know more about knitting bobbles, check out this post.
For the cast on, all you have to do is cast on however many stitches you need for your project. Decide how you want the bobbles spaced, and knit across the row, adding bobbles as you like.
Keep in mind whether or not your pattern starts on the wrong or right side of the fabric. You might need to knit another row after the bobble row in order for your bobbles to appear on the correct side of the fabric. Or, you can even just pop them out onto the other side.
Here is a video of the cast on. Happy knitting, and Enjoy!
