A few tips an tricks on my pattern.

1) if you want you want to use non plastic eyes
If your going to give this to an infant or small child.
Here is the pattern for that:

Non-plastic eyes (make 2)
Rnd 1: Make Magic circle (6 stitches)
fasten off leaving long tail for sewing on.
I hope that helps.

2) When you sew on all the eight legs.
Try to sew them on with even spacing, so that it won’t have a bunch of tentacles clumped together on one side and a few on the other.

3) If you want to make it bigger.
Go ahead and try, I would suggest though that every rnd you increase, try to add an extra 2 sts to the legs/tentacles.

4) On selling this.
You have full permission to, as long as you give me credit of the pattern that you used.
