Cardstock shown is from October Afternoon's Public Library collection - Card Catalog cardstock specifically. I cut the drawers apart for a project...
...and discovered various hardware fits perfectly over the window - top shown is from the store - small label holders and idea-ology Mini Fasteners, and the bottom one is Graphic 45's Ornate Label Holders (used the brads that come with the package). Hope your week is off to a great start!
