Vilene H630 is the thinnest iron-on pellon (fusible fleece).    It is ideal for quilts & patchwork projects like wall hangings or table toppers, and bagmaking as well but it's too lightweight to give any stand-up support I think. A little extra body to a pocket would be great. 

Our H630 is 90 cm wide

It is best used with lightweight to medium-weight fabrics.
Vilene H630 is very easy to iron and is washable and dry-cleanable.

Tip:   Never iron directly on the Vilene, as the iron will burn it.  Always iron on the fabric side.  It is also important to spot-iron your interfacing, which means placing your iron on an area and letting the heat melt the glue before moving it to another area.  Once all the area has been spot ironed, you can move your iron over the fabric as you would normally.
