Has anyone had success converting patterns for non-stretch fabric to
stretch fabric? The pattern I'm considering is for a 3+ piece-cup bra
(the + being a side shaper panel). Just the cups need converting, not
the frame. I kind of wondered whether it might be doable with
Photoshop using the "Image Size" tool. Basically
1) Scan each pattern piece (minus seam allowances) with the grain line
vertical and crop until each side of the window touches the pattern.
Read the length and width measurements.
2) Determine the fabric's percentage of stretch lengthwise and
crosswise. Compute the desired finished measurements and input
3) Photoshop will redraw the image with the proper proportions. Add
SA's back on.
Does this sound right?
One big question is whether the fabric will stretch to its maximum
when worn normally. (Do people who work with stretch know of any rule
of thumb?) The purpose of this is so that the garment provides more
"give." At a guess I think I should assume about 85% of maximum.
Does anyone recommend higher or lower? Does anyone think I should
only stick to 4-way stretch fabrics, the kind that are guaranteed to
have the identical stretch even in diagonal directions? I have no
clue about that...
Any thoughts appreciated!!
