These della Q Mesh + Zip pouches are really easy to use. You can put your small notions like buttons, needles in the small and large zip pouches. For a small knitting or sewing project, use the extra - large pouch. To save space, just stack the smaller pouches inside the larger one. When it comes to maintenance, you can gently wipe the fabric side with a damp cloth. Avoid using harsh chemicals as they may damage the fabric print or the mesh. If you want to use the linen collection, keep in mind that it might take about four weeks to arrive, so plan your projects accordingly.
