follow this guys youtube page ...................lots of tips and tricks

I can't stand those videos with sub titles. Would much prefer a tutorial on here + I think more how to guides on here would be good.

Thanks anyway

I use various methods depending on application to create roll and pleats (aka tuck and roll ). I find this works best: Layout material draw lines 3/4" greater than pleat size ( 2" pleat mark 2 3/4 , 3" pleat mark 3 3/4 etc. ) glue material onto sew foam usually 3/8". Sew all the lines thru the material and foam then fold on the line and sew at 3/8" from folded edge. Some tricks: glue material to 1/8" foam and lay on top of 3/8" foam without glue. This allows pleat to puff up; Draw and sew lines with material stretch(selvage to selvage) This way when pleat is pulled side to side it doesn't stretch thereby eliminating it to flatten out.

I sometimes do the old school cotton stuffed pleats.Very time consuming.

Recently did some with the leather glued to foam, cut into strips, then sewn back together.First time I've done it this way but it worked well and was a lot quicker.

Yeah I find that exact method by far the easiest and least time consuming ...achieves the same finish too.
