I'm newer to making "3d" projects such as bags and purses. One thing that has been of constant frustration to me is the techniques people like to use to design and sew their gussets together. I can't find many good videos and have searched hi and low. I understand how the concept works, but the trouble I find is that many videos offer a pattern in which the holes are premarked. At this point I am quite capable of copying a pattern, but for my own knowledge I would like to know how people like to sew gussets when they are not following a pre-designed patterned so I can create my own designs.
Do you like to pre-punch your holes in both the gusset and the body? Mark the points where the hole should go, either with a wheel or an iron, attach the gusset to the body, and then stitch both pieces, punch the holes in one piece to use as a guide/lessen the thickness the awl must travel through, attach the pieces, and then finish off with an awl?
Also, if anyone has any good resources, books, videos, posts, on the subject that they could link me to I would greatly appreciate it.
Edit: Also, I find a lot of tutorials are sorely lacking on the design phase and get the gusset to the proper length seems challenging, so if there's any insights to that anyone could offer, I would appreciate that as well.
