Just to add if the LBM banners are like the shields, then there is a transparent clear plastic sheet covering the design which you need to peel off. The banner is then sticky so press it, backing paper side up, on to white paper and wet the backing paper. I use a medium paint brush for this. Peel off the backing paper to reveal the banner on the paper which you can then cut out and glue together with PVA around the standard.
Hope this makes sense.
