Always wash my fabrics before using. Recently made a baby quilt and reached into the drawer and snipped fabric from a fabric collection that was tied together with a ribbon and tag. Didn't occur to me that I hadn't washed nor used any of my charm packs or jellyrolls because they are put together in such a tidy package. Also, had used adhesive spray to baste the quilt (it was great) and decided to wash the quilt when completed because it was going to a newborn -- that unwashed fabric bled. So sad. Still haven't figured out what to do with the jellyrolls, etc. because they will be difficult to prewash.
