Making a basic paper pattern.

Fig.1 - Using a ruler and knife.
Use a stiff, heavy paper or card (100gsm and above)if possible.
Use plain, uncoloured and clean paper only or you will mark your work piece.
Most leather goods are symmetrical and can be designed using a half-pattern opened out to give the full shape.
It is important to make the paper perfectly square to ensure symmetry in your finished work.
1) Fold the paper in half and turn it so the fold is at the bottom.
2) Using a steel rule and a knife mark one of the set of limits of the pattern to be produced.
See Fig.1.
Fig.2 - Lining up two marks.
3) Open the paper and lay it flat.
Use the steel rule to line up two marks across the fold and cut this side of the pattern off.
Discard the waste.

See Fig.2.
Fig.3 - Lining up the remaining two marks.
4) Do the same with the other two marks.

See Fig.3.
Fig.4 - Marking half of the second dimension.
You should now have a piece of paper with square edges cut to one of the size limits of the pattern.
5) Re-fold the paper along the original line and put the fold to the left hand side.
Use the steel rule and knife to mark HALF of the second of the size limits of the pattern towards the top of the paper.
Do the same towards the bottom being careful to use the same measurement.

See Fig.4.
Fig.5 - Making the final cut.
6) Now turn the rule to line up these two new marks and cut off the waste paper.
Your pattern blank should now reflect the outer limits of the finished item when opened out.
7) Re-fold the paper the opposite way to the original crease to check that it is accurate.

You can now use the folded paper to mark out a half design and cut it symmetrically before opening it out and cutting around it.
