The draft instructions I read say that for paper filing you print off the 1040 and the applicable schedules, and cut the 2 1040 pages to the applicable post card length. Then put the 1040 pages back to back with the printed side out and scotch tape three of the sides leaving one side untaped. Then you cut the schedules leaving only the printed information, insert the schedules between the 2 1040 pages and scotch tape the 1040 shut. Affix the proper postage and mail to the Bone, Idaho IRS service center.
