I like the light weight ones, I do sew through and around them.
Personally I do not care for steam a seam, it is sticky on both sides, I have dogs in the house and... sure enough, there is an impossible to remove black doog hair tha shows through! Grr, happens everytime. Steam a Seam is a good project, just not for me. I like fusable web, with no paper backing at all. Most hate it.
Before you buy a product, check it out. See if you can carefully peel the paper backing off just a tiny bit. If it is stuck so hard that you cannot remove a little, it has been my experience that it may NEVER come off, yup I have had that happen, too.
