Good morning, looking for some inspiration!. Had 2 windows put in years ago in side wall of garage and the builder installed the lintels set back 20mm. I need to face the lintels with something. Brick slips are 20mm so not enough depth. I can buy 10mm slips but cost is prohibitive ie £50 to ship £70 worth of slips. Anyone got any bright ideas as to what I can do with this? thanks in advance
