I checked my design stash and found that AnntheGran and EmbroiderThis have several cute spider/webs. There is also one in the Cuties designs.
My favorite one with a cute spider is on the Amazing Embroidery Designs site. Design by Sick has two sets of spider/webs but unless you follow their hourly freebies they cost money but they are very pretty and very reasonably priced.
Hope this helps

Thanks for asking; my DH college mascot is a spider, sometimes depicted with a web.
