Hi Tanya;
I've seen this before...and unfortunately whenever two seperate materials are joined there is that area....if the density is higher it really doesnt show much at all when bonded down securely.
you could have hair added to the front area to try and hide the join or you could go with all one material. when going from french lace to sfs lace, the join is much less noticeable because the two materials are so similar...but I-lace is much thicker than the regular lace on your system, that it makes for a more obvious join as you can see.
