1pc Random Push Bubble Toy

initially I bought this pop it toy for my son but ended up using it for my knitting and crochet patterns. I have found it more reliable and easier to see than the typical counters for yarn projects. I can quickly push a bubble with my hook, needle, or finger. I also like it because it is really easy to see where I am if I have eight sets of four rows, by counting the sets across, and the four rows for each set going down.

Thank you for your feedback.
