All of the Angelina range is packed in 10 gram units.
There are two seperate catagories, Heat Bondable and Non Heat Bondable, Both can be freely added in small quantoties to blends to give sparkling highlights.
The heat bondable will fuse to give an iridescent sheet if placed between sheets of baking parchment and ironed. The precise temprature will be found by starting with a cool iron and increasing the temprature until the fusing heat is reached. As all irons are different this method will not overmelt the fibres. This fusing property can be used to trap non fusing fibres to get interesting results.
Both types work well in combination in small amounts with other fibres either handspun, wet felting or needle felting. A little goes a long way.
