I ordered a draft copy of my most recent publication, and inside the dust jacket were white spaces to be used for....what? And how do I access them? I've tried everything possible to even FIND the flaps inside and cannot. Please help.
The flaps should appear in the cover designer, to the far left and right of the front and back cover. If you create a revision of your book and advance to the cover wizard, and these flaps are not appearing there, you should create a support case with us here:
You can also download a cover template with the flaps, prepare it in Photoshop, print the PDF and upload that to Lulu. In this case it would have to be perfectly sized and include the barcode.
