If its about economy, I reccomend buying a bottle of Liquitex matte medium, and some Liquitex (or daler rowney) Acrylic inks, and some flow aid. (
Tbh you may already own matte medium and flow aid for other jobs)
This would set you back maybe £10-15 tops and give you considerably more than £15 worth of wash from
GW at £2.40 per 12ml. Just will take a little playing around to get the colour matched up exactly.
With more colours of ink, youl not really need to use a
GW wash ever again. I use both though; for just a little bit I use a
GW pot out of convinience, for jobs needing large amounts I mix it up.
edit; as I price checked that
GW wash, I noticed that on the
GW site all the images of washes have clear lids... none of them actually do... theyre black tops right?
