No worries.
Here's a quick overview of the process.
Making Wattle at speed is just a case of doing the opposite of what you'd expect. Rather than weaving the horizontal elements between the vertical elements. You weave the vertical elements through the horizontal ones.
I've used cocktail sticks for the picture but absolutely anything can be used from wire,to twigs.
As for the main part I've used cereal packet card. But a good quality paper or thin sheet plasticard will work too.
I've used a blunt blade( as it's all that's in the house and I'm not allowed out
) definitely use a brand new blade.
It's simply a case of drawing a series of horizontal lines spaced at a distance your comfortable cutting at 1.5-2 mm is reasonably repeatable.
You need to leave a vertical strip at either end of the horizontal lines around 5mm at each end. Then cut along each horizontal line ensuring you don't cut through the 5mm strip at each end.
After which you should have a series of horizontal strips attached at either end to the 5mm strip.
Once you've done this it's simply a case of weaving the verticals in and out of the horizontal strips .
Then dress the ends of the verticals to your personal taste.
Once you've the wattle in place then a thinned layer of PVA. ( I use Mod podge)
Once you've tried it and got the aesthetics right with strip width and number of up rights per inch. (To your personal taste) it really does take minute's to make.
