Great tool
Great tool to make metal crochet hooks fit and feel better in your hand. It set in my hand perfectly, and my hand did not get tired like it did when I didn’t.
Worth the short time it took to come from Canada.

I used the slim white gripeaze already and loved it
I used the slim white gripeaze already and loved it, felt so good and stable while using, we are in the process of moving so was only able to use for a little bit, I can’t wait until I utilize it even more!
We hope to be settled in our new house by the middle of April, and I can get back into crocheting!!
And hopefully post a picture of actually using everything I’ve bought from you

It doesn’t get any easier than this! These are high quality yarn needles and the open “eye” of this self-threading darning needles make them indispensible. They are the best darning needles especially for thick yarn. The yarn just slips into the eye of the needle so a separate neede threader is not needed any longer. I highly recommend the Self Threading Darning Needles!

These yarn leashes are the best solution to keep your yarn fom slumping down into itself. They have multiple uses making them a great addition to anyone’s crochet/knitting tool box.

Reign In Your Skeins!
these Yarn Leashes are the hot ticket for keeping your skeins of yarn from unraveling as you use it. Whether you use it for center pulling your yarn skeins or for keeping your yarn from slumping down on itself on the quad spinner the Yarn leashes are up to the task. Simple ad easy to use and they work! They work very well. I highly recommend these Yarn Leashes to every fiber artist!!!
It is a winner! Works as advertised and is such a fun toy for yarn

Aspen Lyn Outlet
Exactly what I was looking for and more!
I absolutely love this product, it was exactly as described, I contacted the owner for help choosing and she was so helpful. I got the one with all of the attachments and it was so worth it. She even thought of adding helpful guides on each of the 4 bases for multiple crafts, which I didn't know was on the device. 10/10
