Just thinking - maybe someone can verify (or clarify) my thoughts -
If one is reducing or enlarging pieces on a copier that have no seam allowances, the result should be what one wants.
If one is reducing or enlarging pieces on a copier that INCLUDE the seam allowances, should one remember to modify the seam allowances to 1/4 inch? (Because the seam allowances would also be enlarge)
Enlarging Example: If I have a pattern piece that is 4.5 x 8.5 - and it finishes to 4 x 8
and I want to double it to finish to 8 x 16 - I need pieces that are 8.5 x 16.5 - ???
But if I DOUBLE the original piece on the copier, it will result in a patter that is 9 x 17 - which would not work out well.
Reducing Example: If I have a pattern piece that is 8.5 x 16.5 (finished size 8 x 16) and reduce it by 50% - that would give me a pattern that is 4.25 x 8.25 - and it should be 4.5 x 8.5
So then I would need to ADD to the seam allowances? because the reduction would have also reduced my seam allowances.
Or would it work to just enlarge/reduce the pattern pieces and correct the seam allowances to 1/4 inch ?
