I know it's been a long wait. Thank you for your patience!
Our new marketplace platform is not ready yet, even though we have new design and some new pages built for the new site. With all the delays that we had in the past, I am not going to mention any dates. All I can say is that we are working on it and that the new Supplies marketplace will most likely be launched at the same time as the redesigned iCraft marketplace.
I wanted to offer you to sell your crafting supplies on the current iCraft site. Would that work for you if we created a category for "Craft Supplies"? This would be a temporarily solution until we have the new Supplies marketplace and migrate all your items there? You can sell supplies in a separate store or in the same store that you currently have. Feel free to email us to discuss your preferences. I could also share with you our new Supplies site design to get your feedback on it.
