I've been scrapbooking for 20 years and have used lots of different adhesives. I have used Herma Dotto repositionable tape runner for years and love how you can lift stuff up to fix it, wipe off excess with a finger and it becomes permanent. The refills are cheap and they go a long way. BUT, now everywhere I look is out of stock and I'm worried they won't get them back. I've never tried the ATG guns because they are GIANT and seem so bulky. What repositionable adhesive can you recommend?
