The Studio+ Tote is not only our biggest project bag but it's also so much more. You can easily organize and carry all of your supplies for very complex or very large projects or you can use it for many smaller projects while also keeping them organized. The Studio+ Tote stands up on its own, seals shut with a drawstring closure, keeps colors and projects separate with pockets and yarn guides, and protects your notions and projects with an interfaced body and a durable canvas box bottom! But wait! We aren't even to the good part yet. The Studio+ Tote is also our most flexible tote: it can be expanded by clipping in Studio Tots which are water bottle sized bags that can hold all sorts of goodies keeping them separate and organized. It truly is a marvel and a wonder to watch in action. It's stylish too.
