Be-Form is a foam-like volume interlining, specially developed for bags. Moreover, the F1 version can be fused to the fabric. Bye bye thick seams
Be-form is very similar in structure to Style-vilfrom Vlieseline but has a slightly higher density and is slightly thinner (3mm versus 4.5mm). It does have the same strength! A big advantage compared to style-vil, at least for projects where ironing is an option, is that Be-form F1 has an adhesive layer and can therefore be fused on the fabric so that thick seams can be avoided.
Pressing is done with the be-form at the bottom, the (shiny) glue layer at the top. Place the fabric to be reinforced on top. If ironing on that fabric is not an option (e.g. in the case of synthetic leather) then iron on the be-form but gradually increase the temperature (and possibly steam) until the adhesive adheres.
Price per 10cm, with a minimum order of 20cm.
