I`m not 100% sure of what you mean..... most people who want to, say, make a partial or two from a system , will cut `across`..... Debbie is well-used to cutting/adjusting systems...why not drop here an e mail ? She`s very helpful.... just tell her you got her details off here ...
[email protected]... I think you are referring to `Darts`which are creases/folds in the lace put in so as to make it follow the individual`s head-contour..... maybe if you attach a pic of the base and show what you propose to do?
