Envelope to fit ATC and PTC March 2026

Hello and welcome to my blog, it has been some time since I last used a keyboard! 

My swap partner liked the envelopes enclosing her PTCs and asked for measurements hence I thought the best way was by blogging the instructions and sharing them on the Clarity FB page. Fervently hoping the instructions make sense!

Thanks for looking in.

ATC and PTC Envelope in Centimetres

(Inches measurements in brackets)

Materials:-

*Clarity Designer Paper 8in x 8in

*Rule

*Pencil

*Adhesive of choice (I used narrow red liner tape)

Instructions:-

1. Cut paper to measure 14cm x 14cm.

(Cut paper to measure 5 and a half inches by 5 and a half inches)

2. Measure 1cm from each edge of paper and join to form a 1cm border on all four sides.

(three eighths of an inch on each side)

   3. From edge of paper, measure 8cm (3 and one eighth of an inch) and mark on pencil line. 

Turn paper by 90 degrees.

4. From edge of paper on second side, measure 6cm (2 and three eighths inch) and mark on pencil line.

Turn paper by 90 degrees.

5. On third side, measure 8cm (3 and one eighth inch) from paper edge and again mark on pencil line. Turn paper to last side.

6. Mark 6cm (2 and three eighths inch) from edge of paper. 

7. Join marks to form central rectangle, ensuring the lines reach the edges.

8. Where the lines intersect, cut away notches on each side.

 9. Fold along each line to form an envelope. 

10. Erase pencil lines. Add glue of choice and fold to create envelope. 

*To neaten, corners may be rounded with a corner punch. 

I do hope the instructions are clear as it's some time since I blogged and with a brand new laptop, a double challenge. 

Happy crafting,

Best wishes,

Shelagh xx
