Solutions from This Week's Puzzles
(Disclaimer: This is not scientific feedback; these solutions are not officially endorsed by the Foldit scientists.)
Puzzle 1858: Symmetric Trimer Design
Personally, I went with a 4-helix design for this puzzle, and it seems like that's what a lot of the highest scoring solutions did. But there were also a couple of 3-helix designs, and even some sheets!
Puzzle 1860: Refinement R1040
The highest scoring solutions for this puzzle kept two medium-sized sheets lined up and folded the rest into short helices around a core.
Compare this to some of the intermediate solutions. Although these folds are okay, they had some minor problems: some loose helices and poor scoring ends.

This week's most beautiful fold comes from Formula350 for his Borromean rings! This would never fold up in real life, but wow, is it pretty!
Today’s Master Folding Tips
Beginner: Don't be afraid to reassign your secondary structures to different sheets and helices! While this might seem like you're "changing the puzzle," you're really just making a suggestion for what shape the protein should take, and this suggestion can help your other tools better serve you. Try a bunch of different secondary structure assignments and use Ideal SS on them afterward, then see how this new arrangement might be easier or harder to fold. Play around with it, Foldit is about experimenting!
Intermediate: If you haven't learned to use Backbone Pins yet, I highly recommend it. This tool, hidden away in the view options, gives you more control over wiggling than CI alone. A locked pin is similar to a ZLB, it will keep your wiggle locked to that spot, while moving everything else more.
Expert: Although it might seem like more hbonds means better binding, hbonds at the interface don't actually add to the strength of the bind, since they aren't much stronger than these atoms simply binding to water. What use are interface hbonds then? Their purpose is eliminating BUNS. The real strength of your binding comes from hydrophobic interactions, shown in the Hiding and Packing subscores, and your hbond network gives the bind its specificity.
