The staples I pulled out were of thin gauge, like what you might use to staple paper. I figured some sort of special gun was used. I am just getting started and on a variety of old family heirlooms so a little of this and a little of that. I saved the cardboard tacking strip. I have some small nails- like brads except they have a head and I thought I could cut some tiny rectangular squares (3/8" x 3/4") from a tin can and punch 2 holes in each end and place that "washer" over the tack strip and then the said nails. I have some carpet tacks but they seemed pretty heavy, are the 4 smaller gauge? Any idea what was used before staple guns? Thanks.
