Follow the first-letter project
MFL combines this pocket with FL01 and FL02. Arrange the paper pieces before gluing, leaving room above the pocket to reach the notes.
Keep one short reply
Use a loose card to hold a reply or a small introduction. Try one layer first; this flat pocket has no expanding gusset and is not a promise of multi-card capacity.
Glue the tabs to the back
Cut both separate pieces. Fold the three tabs behind the front and glue them to the marked area on the printed back. Leave the top open. The nominal glue-free width is 82 mm; usable space still depends on folding, glue and paper thickness.

Digital candidate r0.10. Printing, paper thickness and assembly fit still need physical checks.
Fold and fit notes
Cut solid outlines, fold dashed lines and apply glue only to hatched GLUE areas. Keep the opening clear. Check the 50 mm ruler before cutting.

Target card compatibility is a test plan, not a verified fit claim.

Choosing and using this printable
Is this an envelope?
No. It is an open-top pocket with no closing flap. The download includes its back and front, but no separate note or envelope.
Are FL01 and FL02 proven to fit together inside?
They are intended project companions, not a verified loaded-capacity claim. FL01 adds a fold and extra paper thickness. Actual insertion, removal and capacity need a physical trial.
File notes
AI-assisted illustrations; text, linework and millimetre layout are controlled separately. The previews are rendered from the PDF.
Revision r0.10: Separate back and front widened to 94 mm; 6 mm tabs retained. Nominal glue-free channel 82 mm for a 78 mm card. Original raster artwork unchanged; physical fit untested. Physical evidence is still pending for this revision.
