I always blame it on the designer, but I know it's really a "user error." Make sure you are using quality stabilizer and you're fabric is hooped tight. It does matter if your machine is on a countertop that cannot shift vs. a table that can shift/hop/jump. When all else fails, have colored pigment pens to hide the small gaps. It really works! It looks like your little monkey can just be filled in with a brown pigment pen. Try it! :)
Good luck! :)
